Question 255155

1) 3x + 3y = 14
2) 3x - 2y = 10

Multiply both sides of equation 1) by 2 and equation 2) by 3. Then we have:

1a) 6x + 6y = 28
2a) 9x - 6y = 30

Adding like terms of the two equations above we eliminate y:

15x + 0y = 58
15x = 58
x = 58/15

Substitue 58/15 for x in either equation 1) or 2) and then solve for y.
