5y - 2x = -15
x= 3y+ 8

5(-1) - 2(-5) = -15 . y=-1 x=-5

Step-by-step explanation:

5y - 2x = -15

5y - 2 (3y+ 8) = -15

5y-6y-16=-15

-y-16=-15

   +16 . +16

-y=1

(-1)y=1(-1)

y=-1

5(-1) - 2x = -15

-5-2x=-15

+5 .      +5

2x=-10

x=-5

5(-1) - 2(-5) = -15

-5-(-10)=-15

-15=-15

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
