4x + 3y = 6 ⇒ -24x - 18y = -36
-6x - 2y = -24 ⇒ -24x - 8y = -96
 -10y = 60
 -10 -10
 y = -6
 4x + 3(-6) = 6
 4x - 18 = 6
 + 18 + 18
 4x = 24
 4 4
 x = 6

The orderd pair (6, -6) is a solution of the system of equations.

Change x with 6 and y with -6

4x+3y=6
4*6+3*(-3)=24-18=6

-6x-2y=-24
-6*6-2*(-6)=-36+12=-24

answer is yes
