Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.
2x+4=4x
According to the question, we have to solve the algebraic expression and find the value of x.
As the above expression is algebraic expression and it is defined as the expression which is made up of variables and constants, along with algebraic operations like addition, subtraction, multiplication and division.
To solve the algebraic expression, we have to arrange the variable term in one side and constant term in one side and then solve accordingly.
Rewrite the given expression,
Now, to solve further stepwise solution given as below,
Step 1- Transfer 4x from right hand side to left hand side and 4 from left hand side to right hand side,
Step 2- Now subtract the expression and write as -2x in the above expression,
Step 3- As in the both sides, there are minus sign ,so , to remove the sign just multiply with negative sign and we know that ,
Step 4- to eliminate the coefficient from the variables term, divide by 2 in both sides, we get
Step by step
Solved in 3 steps
