3x+4y=4
x-y=13
...
Multiply the second equation by 4
4(x-y=13)
4x - 4y = 52
Add to the first equation
3x+4y=4
4x-4y=52
...
3x + 4x + 4y + -4y = 4 + 52
7x = 56
...
Multiply the second equation by -3
-3(x-y=13)
-3x+3y=-39
Add to the first equation
3x+4y=4
-3x+3y=-39
3x + -3x + 4y + 3y = 4 + -39
7y = -35
