The expression is simplified to s = -5/ 4

What are algebraic expressions?

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

They are also made up of mathematical operations such as addition, subtraction, multiplication, division, etc

Given the expression;

42 = 14{ 4 + 4/ 5s}

Divide both sides by 14

42/14  = 14{ 4 + 4/ 5s}/14

3 = 4 + 4/ 5s

3 =   20 + 4s/5

cross multply

15 = 20 + 4s

collect like terms

15 - 20 = 4s

-5 = 4s

Make 's' the subject

s = -5/ 4

Thus, the expression is simplified to s = -5/ 4
