3-8x-\left(-5\right)+6-7x+3=7x-\left(5x+9-3\right)
To find the opposite of 8x-5, find the opposite of each term.
3-8x+5+6-7x+3=7x-\left(5x+9-3\right)
The opposite of -5 is 5.
8-8x+6-7x+3=7x-\left(5x+9-3\right)
Add 3 and 5 to get 8.
14-8x-7x+3=7x-\left(5x+9-3\right)
Add 8 and 6 to get 14.
14-15x+3=7x-\left(5x+9-3\right)
Combine -8x and -7x to get -15x.
17-15x=7x-\left(5x+9-3\right)
Add 14 and 3 to get 17.
17-15x=7x-\left(5x+6\right)
Subtract 3 from 9 to get 6.
17-15x=7x-5x-6
To find the opposite of 5x+6, find the opposite of each term.
17-15x=2x-6
Combine 7x and -5x to get 2x.
17-15x-2x=-6
Subtract 2x from both sides.
17-17x=-6
Combine -15x and -2x to get -17x.
-17x=-6-17
Subtract 17 from both sides.
-17x=-23
Subtract 17 from -6 to get -23.
x=\frac{-23}{-17}
Divide both sides by -17.
x=\frac{23}{17}
Fraction \frac{-23}{-17} can be simplified to \frac{23}{17} by removing the negative sign from both the numerator and the denominator.
