Question

Which ordered pair is a solution of the equation ?

4x-1=3y+5

A) only (3,2)
B) only (2,3)
C) Both (3,2) and (2,3)
D) Neither

Answer 1

A) (3, 2)

Explanation:

First, solve for x to make it into a linear equation.

3y = 4x-6

y=4/3x-2

Plug in the coordinates to see if they work:

2 = 12/3-2

3 = 8/3-2

Only the (3,2) pair works

Answer 2

A.

Explanation:

4(3)-1=11

3(2)+5=11

11=11
