3x-11 for x=9
x - 7 - 9 = -3x - 16 = -3x = 13
24 = 3x + 9 -9 -9 Subtract 9 from each side15 = 3x/3 /3 Divide 3 from each side5 = x You are left with five equals X
172=x
3x + 9 = 42 3x = 33 x = 11
3x-y=9 y=3x-9
3x-11 for x=9

3x + 9 = 42 3x = 33 x = 11
3x-6 = 21 3x = 21+6 x = (21+6)/3 x = 9 You shouldn't ask us to solve your math homework.
Watch closely:6x = 3x + 27Subtract 3x from each side:3x = 27Divide each side by 3:x = 9
3x - 24 = 3Add 24 to each side of the equation:3x = 27Divide each side by 3 :x = 9
3x2-9x = 0 x(3x-9) = 0 x = 0 or x = 3
