y = -1.4
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
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
y = -1.4

Solve the equations by moving the variable to one side : 7y + 11 = 3y + 25 (subtract 3y from each side) 4y + 11 = 25 (subtract 11 from each side) 4y = 14 Y = 3.5
6x - 4y
2x-7y=14 2x-14=7y from this equation the slope is 2/7
6x+7y=-6 3(-2x-3y=2) +________ -2y=0 => y=0 Therefore x=-1
6x plus 4y
-7y + 4y = -3y
