Answer:
(x, y) = (-10, -7)
Step-by-step explanation:
#1 Multiply the first equation by 7
#2 Then multiply the second equation by 5
1. 14x - 35y = 15
2. 10x - 35y = 55 (-
---------------------------
4x = -40
x = -10
Then go back to equation one and replace "x" with -10
2(-10) - 5y = 15
-20 - 5y = 15
-5y = 15 + 20
-5y = 35
5y = -35
y = -7
The answer is
(x, y) = (-10, -7)
Hope this helps!
Have a nice day!
