It is 9x

7x-4=9x+10-14=2xx=-7

7x = 18 - 2x 7x + 2x = 18 9x = 18 x = 2

9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6

2x + ? = 9x9x - 2x = 7xso...2x + 7x = 9x

- 7x + (9x - 3) = - 7x + 9x - 3 = 2x - 3

2x+3 = 9x 3 = 9x-2x = 7x 7x = 3 x = 3/7

2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x

9x+18 = 180 9x = 180-18 9x = 162 x = 18

2x+3=9x =>3=7x =>3/7=x

2x + 24 = 9x - 39= 2x + 63 = 9x= 63 = 7x= x = 9

9x-3y=63 7x-3y=45 -3y=63-9x -y=21-3x y=-21+3x 7x-3(-21+3x)=45 7x+63+9x=45 7x+9x=45-63 16x=-18 x=-1.125 y=-21+3(-1.125) y=-24.375 (-1.125,-24.375)

7x + 19 = -2x + 55Add 2x to both sides:9x + 19 = 55Subtract 19 from both sides:9x = 36Divide both sides by 9x = 4

9x-8=7x-3 9x-7x=-3+8 2x=5 x=5/2 x=2.5

2x+3=9x-2x -2x3=7x/7 /73/7=x

2x+5=11 2x=6 x=3

7x = 4x - 93x = -9x = -3

answer is 4 7x+19=-2x+55 +2x +2x 9x+19= 0 55 -19 -19 9x = 36 9 9 =4

8x+9=9x-18+9 = 8x+9=9x-9 = 1x=0 (:

x = 4 9x = 7x + 8. Subtract 7x from both sides. This leaves 2x = 8. Then divide both sides by 2 to get x by itself. So, x = 4.

9x+8=7x+22 To solve for x, combine like terms. (Subtract 7x from both sides, and subtract 8 from both sides. This will give you: 2x=14 Divide both sides by 2. The answer is x=7.

2x+4+7x-4 is the same as 9x

7x + 6

9x2 + 7x = 2 9x2 + 7x - 2 = 0 9x2 + 9x - 2x - 2 = 0 9x(x + 1) - 2(x + 1) = 0 (9x - 2)(x + 1) = 0 x ∈ {-1, 2/9}

7x - 9x = -2x
