Solve the system of equations 5 – 5y = 0 and 4x – 6y = –18 by combining the
equations.

y=1, x=-3

Step-by-step explanation:

Isolate y for 5-5y=0

5-5y=0

Subtract 5 from both sides

5-5y-5=0-5

Simplify:

-5y=-5

Divide both sides by -5

-5y/-5=-5/-5

Simplify

y=1

Substitute y=1

4x-6*1=-18

Simplify

4x-6*1=-18

Simplify  4x-6*1

4x-6=-18

Add 6 to both sides:

4x-6+6=-18+6

simplify

4x=-12

Divide both sides by 4

4x/4=-12/4

Simplify

x=-3

The solutions to the system are

y=1, x=-3
