Answer:
(-2,3)
Step-by-step explanation:
y=2x+7
y=-4x-5
Multiply the second equation by -1 so we can add them and eliminate y
-y=4x+5
----------------
0 = 6x+12
Subtract 12 from each side
-12 = 6x+12-12
-12 = 6x
Divide by 6
-12/6 = 6x/6
-2 =x
Plug this into the first equation to solve for y
y = 2(-2) +7
y =-4+7
y=3
