7y-3y-14=14
4y-14=14
4y-14+14=14+14 (adding 14 on both side)
4y=28
(4y)/4=28/4 (dividing by 4 on both side)
y=28/4=7

y = -1.4
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
7y = 3y - 12 4y = -12 y = -3
3y=7y+24.4 First, try to get all the y-terms on the same side of the equation. Easily done here by subtracting 7y from both sides 3y-7y=7y-7y+24.4 -4y=24.4 Now divide by -4 -4y/-4=24.4/-4 y=-6.1
