Answer:
x = 5/6
y = 8/5

Step-by-step explanation:

Multiply the bottom equation by 2 so you can cancel out
12x + 15y = 34
-12x + 10y = 6

Add the equations together to cancel out x
25y = 40

Divide by 25 to find y
y = 8/5 or 1.6

Substitute y into the original equation
12x + 15*1.6 = 34

Solve for x
12x + 24 = 34
12x = 10
x = 5/6 or 0.833333

To check substitute x and y into the second equation

Hope this helps :)
