Answer:
(3, -1) or x=3, y=-1
Step-by-step explanation:
using substitution for y, the first equation becomes 3(-2x + 5) - 2x = -9
distribution of the 3 gets your equation to be -6x + 15 - 2x = -9
from here you combine like terms to get -8x + 15 = -9
from here it's just a two step equation
subtract 15 from both side to get -8x = -24
divide and get x = 3
substitute x in the equation for y to get y = -2(3) + 5
distribution gets you y = -6 + 5, which makes y = -1
to check your work you can just plug in the variables equivalents in the first equation, which upon doing you can see that the answer is indeed 3, -1
