Find x so that (x, - 16) is a solution to 2x + 3y = 12.

30

Step-by-step explanation:

Start with 2x + 3y = 12. Substitute - 16 for y, obtaining 2x + 3 (-16) = 12. Simplify this and then solve the resulting equation for x:

2x - 48 = 12, or 2x = 60.

Dividing both sides by 2 results in x = 30.

(30, - 16) is a solution of 2x + 3y = 12.
