9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
It is 9x
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
7x-4=9x+10-14=2xx=-7
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
2x + ? = 9x9x - 2x = 7xso...2x + 7x = 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
That would depend on the plus or minus values of 7x and 10y of which none have been given.
- 7x + (9x - 3) = - 7x + 9x - 3 = 2x - 3
2x + 3 = 9x start by bringing the 2x over- minus it from both sides 3 = 7x divide 7 by on sides x= 3/7 x = .4285714285714 repeating.
2x + 24 = 9x - 39= 2x + 63 = 9x= 63 = 7x= x = 9
