I am trying to make a code to find x and y using two equations, my equation gives the right x and y but for some reason, it gives multiple 'There is no solution', and then multiple answers (ex x=3, y=4: 5 times).0 This is what I have so far: ''' Read in first equation, ax + by = c ''' a = int(input()) b = int(input()) c = int(input()) ''' Read in second equation, dx + ey = f ''' d = int(input()) e = int(input()) f = int(input()) solution_found = False for x in range(-10, 11): for y in range(-10, 11): eqn_1_solved = ((a * x + b * y) == c) eqn_2_solved = ((d * x + e * y) == f) if eqn_1_solved and eqn_2_solved: solution_found = True x_solution = x y_solution = y if solution_found: print(f'x = {x_solution}, y = {y_solution}') else: print('There is no solution')
Operations
In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.
Basic Operators
An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.
Division Operator
We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:
Modulus Operator
Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.
Operators
In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.
I am trying to make a code to find x and y using two equations, my equation gives the right x and y but for some reason, it gives multiple 'There is no solution', and then multiple answers (ex x=3, y=4: 5 times).0 This is what I have so far:
''' Read in first equation, ax + by = c '''
a = int(input())
b = int(input())
c = int(input())
''' Read in second equation, dx + ey = f '''
d = int(input())
e = int(input())
f = int(input())
solution_found = False
for x in range(-10, 11):
for y in range(-10, 11):
eqn_1_solved = ((a * x + b * y) == c)
eqn_2_solved = ((d * x + e * y) == f)
if eqn_1_solved and eqn_2_solved:
solution_found = True
x_solution = x
y_solution = y
if solution_found:
print(f'x = {x_solution}, y = {y_solution}')
else:
print('There is no solution')
Your question concerns how to construct Python code to solve two equations with two unknowns. Your present code is nearly correct, but it has two problems:
- It does not handle the case where there are multiple solutions correctly.
- It prints "There is no solution" for all of the x and y values that it iterates over, even if there are solutions.
