2x+4+7x-4 is the same as 9x
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
-4(7x-3y-z)-(-6)(9x-z+2)
The expression simplifies to: -7x-4
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
2x+4+7x-4 is the same as 9x
7x-4=9x+10-14=2xx=-7
It is -9x plus 5.
answer is 4 7x+19=-2x+55 +2x +2x 9x+19= 0 55 -19 -19 9x = 36 9 9 =4
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.
7x + 19 = -2x + 55Add 2x to both sides:9x + 19 = 55Subtract 19 from both sides:9x = 36Divide both sides by 9x = 4
(7x - 4)(7x + 4).
-4(7x-3y-z)-(-6)(9x-z+2)
11 + 9X
102 +9x +4 = 9x + 106, which is in its simplest form.
The expression simplifies to: -7x-4
