Question

Which pair is a solution of

2y=6+3x ?

A. (-1, 1 and 1/2)

B. (-1, 9/2)

C. (-1, 3)

D. (3, 2)

Answer 1

Only way I know of to solve this is trial and error. You have to run through all of them to get the right pair :P

(x, y)

Let's try choice A.

2(1.5) = 6 + 3(-1).

3 = 6 + (-3).

3 = 6-3.

3 = 3.

WHOA! We got it on the first try!

Therefore, choice A is a solution for 2y = 6 + 3x
