4y+2 = 2y+6 4y-2y = 6-2 2y = 4 y = 2
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
4y + 4 = 2y + 12Subtract 2y from each side of the equation:2y + 4 = 12Subtract 4 from each side:2y = 8Divide each side by 2:y = 4
4y + 4 = 2y + 12Subtract 4 from each side of the equation:4y = 2y + 8Subtract 2y from each side:2y = 8Divide each side by 2 :y = 4

-6y + 14 + 4y = 32-2y = 32 - 14-2y = 18y = - 9
4y+2 = 2y+6 4y-2y = 6-2 2y = 4 y = 2
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
4y = 2y + 40 4y - 2y = 2y -2y +40 2y = 40 y = 20 check 4(20) = 2(20) +40 80 = 80
4y + 4 = 2y + 12Subtract 2y from each side of the equation:2y + 4 = 12Subtract 4 from each side:2y = 8Divide each side by 2:y = 4
4y + 4 = 2y + 12Subtract 4 from each side of the equation:4y = 2y + 8Subtract 2y from each side:2y = 8Divide each side by 2 :y = 4
2y = 4x + 4y = 2x + 2

Subtract: 3x - 3x - 4y - 2y = 30 - 6 ie -6y = 24 so y = -4 and x = 14/3
