Solve the system of equations given below y - 15 = 3x -2x + 5y = -3 1. (-7,-6) 2. (-3,6) 3. (-6,3) 4. (-6,-3)

-5(y-15=3x) = -5y+75=-15x

add 15x to both sides and subtract 75 to both sides

-5y+15x=-75

5y-2x=-3

13x=-78

divide 13 to both sides

x=-6

y-15=3(-6)

y-15=-18

add 15 to both sides

y=-3

so the answer is  (-6,-3)

I hope that this helped you sweetie :)
