Answer:

Step-by-step explanation:

Let's take one of the equations and solve for x. I'll take the first one.

Divide by 13.

Now replace x in the second equation.

Distribute -8

Break down the fraction.

Subtract 

Subtract 6y

Combine like terms;

Solve;

Keep solving;

Multiply by the negative reciprocal of the fraction next to y.

On the right side; 13 and 13 become 1. 300/30 = 30/3 = 10

After having found y, replace it in any of the equations to find x.

Answer:
(8,5)
Step-by-step explanation:
x=8
5*8-2y=30
40-2y=30 . subtract 40 from both sides
-2y=-10 . divide both sides by-2
y=5
88 * 2 = 176 ;
88 * 3 = 264 ;
88 * 4 = 362 ;
