It is 9x
2x + 24 = 9x - 39= 2x + 63 = 9x= 63 = 7x= x = 9
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 + ? = 9x9x - 2x = 7xso...2x + 7x = 9x

2x + 24 = 9x - 39= 2x + 63 = 9x= 63 = 7x= x = 9
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
answer is 4 7x+19=-2x+55 +2x +2x 9x+19= 0 55 -19 -19 9x = 36 9 9 =4
7x + 19 = -2x + 55Add 2x to both sides:9x + 19 = 55Subtract 19 from both sides:9x = 36Divide both sides by 9x = 4
