<h3>What are algebraic expressions?</h3>
Algebraic expressions are expressions made up;
- Factors
- variables
- terms
- constants
They also consist of mathematical operations such as addition, multiplication, division, subtraction, parenthesis, brackets, etc
We have the expression as;
7.5x = 5.5x + 10
collect like terms
7.5x - 5.5x = 10
subtract the like terms
2.0x = 10
Make 'x' the subject
x = 10/2. 0
x = 5
Thus, the value of x is 5
