Answer:
(x,y) --> (-1, -3)
Step-by-step explanation:
Solve by elimination...
2x - 3y = 7
4x + y = -7 (times 3; so -3y and 3y cancel out)
2x - 3y = 7
12x + 3y = -21
2x = 7
12x = -21
add together...
14x = -14
x = -1
plug x into one of the original equations and solve for y...
-2 - 3y =7
-3y = 9
y = -3
