The difference of x and a number is 6. The other number is x- 6.

x - (x - 6) = x - x + 6 = 6

x - (x - 6) = x - x + 6 = 6

4 + (27 - 12·2) ÷ 2

= 4 + (27 - 24) ÷ 2

= 4 + 3/2

= 4 + 1.5

= 5.5

= 4 + (27 - 24) ÷ 2

= 4 + 3/2

= 4 + 1.5

= 5.5

4y - 6y + 9y = -2
{-2/11}
{-2/7}
{2/7}
{2/11} **Weegy:** y = -2/7 **User:** (x - 3) - 2(x + 6) = -5
{-10}
{-4}
{8} **Weegy:** its -10. wait ill check again **User:** (x - 3) - 2(x + 6) = -5
{-10}
{-4}
{8} **Weegy:** its -10. wait ill check again **User:** 7x + 9 = 6x - 5
x = -14
x = -4
x = 4
x = 14 **Weegy:** 4-7x+10=15-6x-8
4+10=14 and 15-8=7
so now you have...
14-7x=7-6x
- - - - - - - - - - - - - - - - - - - ?
7x+7x
14=7+x
now use opposites to get
-x= -7 which equals
x=7 is your answer. **User:** 17x - 6 + 3x - 5 = x + 11 + 4x
20x - 11 = 5x + 11
20x + 1 = 5x + 11
9x = 16x **Weegy:** 20x-11=5x+11 **User:** An equation _____ has one solution.

7x + 9 = 6x - 5

7x - 6x = -5 - 9

x = -14

7x - 6x = -5 - 9

x = -14

9(x - 2) = 18

9x - 18 = 18

9x = 18 + 18

9x = 36

x = 36/9

x = 4

9x - 18 = 18

9x = 18 + 18

9x = 36

x = 36/9

x = 4
