Answer:
x = 4
y = -9
Step-by-step explanation:
Isolate a variable from one of the equations ( I chose the first equations cuz it's easy): 6x + y = 15 will be y = 15 - 6x
Substitute the above equation in the place of y in the second equations:
-7x -2(15 - 6x) = -10
-7x -30 + 12x = -10
-30 + 5x = -10
5x = 20
x = 4
To find y-value, substitute the x-value gotten in any equation:
y = 15 - 6(4)
y = 15 - 24
y = -9
Hope this helps!
