Question

1. $5(2x + 3y + 4) + 2(3x + y + 6)$

Explanation:

Step1: Distribute coefficients

$5(2x) + 5(3y) + 5(4) + 2(3x) + 2(y) + 2(6)$

Step2: Calculate each term

$10x + 15y + 20 + 6x + 2y + 12$

Step3: Combine like terms

$(10x + 6x) + (15y + 2y) + (20 + 12)$

Step4: Simplify

$16x + 17y + 32$

Answer:

$16x + 17y + 32$
