Question

How do you evaluate?

Answer 1

We evaluate an algebraic expression by the determination of an unknown variable.

Evaluation is a systematic method used in solving most algebraic expressions in mathematics.

Let assume that we have a given algebraic expression where y is expressed in terms of x and;

y = 2x + 5    where (x = 4)

• Here, y and x are the variables;

y = 2(4) + 5

y = 8 + 5

y = 13
