Question

1. simplify each expression.

a. $8x + 4x + 5 - 2$
b. $5y + 10 + 9y - 2x$

Explanation:

Step1: Combine like x terms

$8x + 4x = 12x$

Step2: Combine constant terms

$5 - 2 = 3$

Step3: Combine results (part a)

$12x + 3$

Step4: Combine like y terms (part b)

$5y + 9y = 14y$

Step5: Rewrite simplified expression (part b)

$14y - 2x + 10$

Answer:

a. $12x + 3$
b. $14y - 2x + 10$ (or $-2x + 14y + 10$)
