Answer:
(x, y) = (19, 20)
Step-by-step explanation:
The coefficients of y are opposites, so we can add the two equations to eliminate y.
(-3x +8y) +(-5x -8y) = (103) +(-255)
-8x = -152
x = 19 . . . . . . . divide by -8
Substituting into the first equation, we have ...
-3(19) +8y = 103
8y = 160
y = 20
The solution is (x, y) = (19, 20).
3 over 2 is the simplest form you can put this answer in.

I think because 5 times 4 is 20 so 20 divided by 2 is 10 dividing braces of triangle
