-47 - 15y =-17.....Equation A
-x+ 5y=-13..........Equation B
Solve B for y.
-x + 5y = -13
5y = x - 13
y = (x - 13)/5
Plug y into A.
-47 -15y = -17
-47 -15(x - 13)/5 = -17
-47 -3(x - 13) = -17
-47 -3x + 39 = -17
-3x - 8 = -17
-3x = -17 + 8
-3x = -9
x = -9/-3
x = 3
Now that we know x is 3, plug 3 for x into EITHER Equation A or B (your choice) to find y.
I will let you do that.
