Find value of the unknown variable from the given equation.
Answer to Problem 9GP
Infinite number of solutions
Explanation of Solution
Given:
The Equation:
Concept Used:
In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
Here, for example, 5x + 9 is the expression on the left-hand side, which is equal to the expression 24 on the right-hand side. i.e. 5x+9 = 24 is an equation.
Calculation:
Addition or Subtraction Property of Equality:
If
The property that states that if you add or subtract the same number to both sides of an equation, the sides remain equal (i.e., the equation continues to be true.)
Multiplication and Division Properties of Equality:
If
If
In other words, if two expressions are equal to each other and you multiply or divide (except for 0) the exact same constant to both sides, the two sides will remain equal.
Given the Equation:
Step 1: Open the parenthesis by using Distributive method of multiplication.
When in an equation both sides are equal (example
Thus, the equation
