Answer:

7x-5y=8 multiply by -3

Step-by-step explanation:

Solving for x.  

1 Add 5y5y to both sides.

7x=8+5y

7x=8+5y

2 Divide both sides by 77.

x=\frac{8+5y}{7}

x=  

7

8+5y

Solving for y.  

1 Subtract 7x7x from both sides.

-5y=8-7x

−5y=8−7x

2 Divide both sides by -5−5.

y=-\frac{8-7x}{5}

y=−  

5

8−7x
