9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
10 + 9x
2x+3=9x 3=9x-2x 3=7x x=3/7
3x + 6x +1 = 10 9x = 10 - 1 9x = 9 x = 1
7x - 9x = -2x
9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
It is 9x
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
2x + ? = 9x9x - 2x = 7xso...2x + 7x = 9x
7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
10 + 9x
2x+3=9x 3=9x-2x 3=7x x=3/7
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
- 7x + (9x - 3) = - 7x + 9x - 3 = 2x - 3
2x + 24 = 9x - 39= 2x + 63 = 9x= 63 = 7x= x = 9
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
