it equals 13X.
2x + ? = 9x9x - 2x = 7xso...2x + 7x = 9x
It is 9x

2x + 24 = 9x - 39= 2x + 63 = 9x= 63 = 7x= x = 9
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+3=9x 3=9x-2x 3=7x x=3/7
2x+3=9x-2x -2x3=7x/7 /73/7=x
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
X= -2
2x + 3 = 9x Subtract 2x from both sides: 3 = 7x Divide both sides by 7: 3/7 = x
2x+5=11 2x=6 x=3
