4y-9 = 15 4y = 15+9 4y = 24 y = 6
10y-3=4y+6 10y = 4y + 9 6y = 9 y = 9/6 y = 3/2 y = 1.5
4y + 10 = 22 4y - 10 - 10 4y=12 4y 4y 4y=3
4y + 9The variable is Y. The variable is the letter (the unknown amount)
If y + 3y + 10 = 70, then 4y + 10 = 70, and 4y = 60. We then find that y = 60/4 = 15.
....Well...if you mean 4y + 9 = 17, then the answer is 2.If you mean 4y - 9 = 17, then the answer is 6.5.
y = 2 (4X2=8) +9 = 17
y = 6

4y = 929 4y/4 = 929/4 y = 232.25
4y-9 = 15 4y = 15+9 4y = 24 y = 6
10y-3=4y+6 10y = 4y + 9 6y = 9 y = 9/6 y = 3/2 y = 1.5
X=3 y=2 (3x3) + (4x2) = 17 9 + 8 = 17
4y+y=10 5y=10 y=2
3x+4y = 17 -3x -3x 4y = -3x+17 Divide each TERM by 4 y = -3x + 17 4 4
3x+4y = 17 -3x -3x 4y = -3x+17 Divide each TERM by 4 y = -3x + 17 4 4
4y + 10 = 22 4y - 10 - 10 4y=12 4y 4y 4y=3
