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
