"If 5x+7=-13, then x=-4"
The contrapositive is the inverse and converse of a conditional statement. So, the contrapositive of this statement would be:
"If x does not equal -4, then 5x+7 does not equal -13."

Plug in the first equation into the he second equation
3x-(2x+7)=-9
3x-2x-7=-9
x-7=-9
x=-2
plug in x=-2 into the first equation
y=2(-2)+7
y=-4+7
y=3
answer: (-2,3)
