Answer:
(-4, -3)
Step-by-step explanation:
First divide the second equation by -1. It becomes y = -3x - 15.
Then, substitute this equation into the y of the first equation.
x + 2(-3x - 15) = -10
x - 6x - 30 = -10
-5x = 20
x = -4
Then substitute the x value into the equation x + 2y = -10
-4 + 2y = -10
2y = -6
y = -3
Answer: (-4,-3)
Step-by-step explanation:
(-4)+2*(-3)=-10
-4-6=-10
-10=-10 True
-(-3)=3*(-4)+15
3=-12+15
3=3 True
