3x+5-2x-\left(-4\right)=-x-4-\left(10-x\right)
To find the opposite of 2x-4, find the opposite of each term.
3x+5-2x+4=-x-4-\left(10-x\right)
The opposite of -4 is 4.
x+5+4=-x-4-\left(10-x\right)
Combine 3x and -2x to get x.
x+9=-x-4-\left(10-x\right)
Add 5 and 4 to get 9.
x+9=-x-4-10-\left(-x\right)
To find the opposite of 10-x, find the opposite of each term.
x+9=-x-4-10+x
The opposite of -x is x.
x+9=-x-14+x
Subtract 10 from -4 to get -14.
x+9+x=-14+x
Add x to both sides.
2x+9=-14+x
Combine x and x to get 2x.
2x+9-x=-14
Subtract x from both sides.
x+9=-14
Combine 2x and -x to get x.
x=-14-9
Subtract 9 from both sides.
x=-23
Subtract 9 from -14 to get -23.
