Answer:
(-2,5)
x= -2
y=5
Step-by-step explanation:
I'm going to solve this through substitution
We need a variable by itself (and we also need it to be positive)
We solve for y in the second equation
5x-y= -15
5x+15=y
We can then plug this in for y into the first equation
3x+2(5x+15)=4
and solve for x
3x+10x+30=4
13x= -26
x= -2
We can then plug this value in for x into any of the two beginning equations and solve for y
5(-2)-y= -15
-10-y= -15
-y= -5
y =5
