Answer: (6, 7) x = 6
y = 7

Isolate x in the first equation.
2x = 12 Divide by 2 to both sides
x = 6 Isolated x!

Substitute in (6) for x in the second equation.
(6) - 5y = -29 Remove parenthesises
6 - 5y = -29 Subtract 6 from both sides
-5y = -35 Divide by -5 to both sides
y = 7 Isolated y!

With x = 6 and y = 7:
(6, 7)
