3-2\left(-2\right)-\left(3z-2\right)=-2-\left(6z-2\right)
Subtract 4 from 2 to get -2.
3-\left(-4\right)-\left(3z-2\right)=-2-\left(6z-2\right)
Multiply 2 and -2 to get -4.
3+4-\left(3z-2\right)=-2-\left(6z-2\right)
The opposite of -4 is 4.
7-\left(3z-2\right)=-2-\left(6z-2\right)
Add 3 and 4 to get 7.
7-3z-\left(-2\right)=-2-\left(6z-2\right)
To find the opposite of 3z-2, find the opposite of each term.
7-3z+2=-2-\left(6z-2\right)
The opposite of -2 is 2.
9-3z=-2-\left(6z-2\right)
Add 7 and 2 to get 9.
9-3z=-2-6z-\left(-2\right)
To find the opposite of 6z-2, find the opposite of each term.
9-3z=-2-6z+2
The opposite of -2 is 2.
9-3z=-6z
Add -2 and 2 to get 0.
9-3z+6z=0
Add 6z to both sides.
9+3z=0
Combine -3z and 6z to get 3z.
3z=-9
Subtract 9 from both sides. Anything subtracted from zero gives its negation.
z=\frac{-9}{3}
Divide both sides by 3.
z=-3
Divide -9 by 3 to get -3.
