15y=3x-30
-4x+5y=5 (Ax+By=C)

(-5,-3)

Step-by-step explanation:

I am assuming we need to solve by substitution.

15y=3x-30

-4x+5y=5

First, we solve one of the equations for y.

15y=3x-30

Divide 15 from both sides

y=1/5 x -2

Now, we get the other equation and substitute the y.

-4x+5(1/5 x -2)=5

Simplify

-4x+x-10=5

Simplify

-3x-10=5

Add 10 to both sides

-3x=15

Divide by -3 to both sides

x=-5

Now we get one of the original equations and substitute the x to find y.

15y=3(-5)-30

Simplify

15y=-15-30

Simplify

15y=-45

Divided by 15 on both sides

y=-3

x=-5

y=-3

x always will go first.
