4x - 3y = 17.....multiply by 4
5x + 4y = 60 ...multiply by 3
-----------------
16x - 12y = 68 (result of multiplying by 4
15x + 12y = 180 (result of multiplying by 3
-----------------add
31x = 248
x = 248/31
x = 8

4x - 3y = 17
4(8) - 3y = 17
32 - 3y = 17
-3y = 17 - 32
-3y = - 15
y = -15/-3
y = 5

solution is (8,5) <==
