What are algebraic expressions?

Algebraic expressions are expressions that are comprised of terms, constants, coefficients, variables and factors.

They are also made up of arithmetic operations made up of subtraction, addition, multiplication, division.

To determine the expressions, we have;

1. Let the number be x

We have the expression as;

6x - 8 = x - 7

collect like terms

6x - x = - 7 + 8

5x = 1

Make 'x' the subject

x = 1/ 5

2. Let the number be x

2x = x + 11

collect like terms

2x - x = 11

x = 11

Thus, the values of x are 1/ 5 and 11 respectively.
