<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
