Question

Solve each equation. Show or explain your reasoning.

−3x − 5 = 16

−4(y − 2) = 12

Answer 1

Explanation:

First equation: −3x − 5 = 16

Combine the constants:

-3x = 21

Solve for x using division: x = 21/(-3) or x = -7

Second equation: −4(y − 2) = 12

Reduce this by dividing both sides by -4: y - 2 = -3

Add 2 to both sides, to isolate y: y = -1
