Solve 12=-3(2-2r)-(2r+2)

$$12 = - 3 ( 2 - 2 r ) - ( 2 r + 2 )$$

Solve for r

$$r=5$$

Steps for Solving Linear Equation

Use the distributive property to multiply -3 by 2-2r.

$$12=-6+6r-\left(2r+2\right)$$

To find the opposite of 2r+2, find the opposite of each term.

$$12=-6+6r-2r-2$$

Combine 6r and -2r to get 4r.

$$12=-6+4r-2$$

Subtract 2 from -6 to get -8.

$$12=-8+4r$$

Swap sides so that all variable terms are on the left hand side.

$$-8+4r=12$$

Add 8 to both sides.

$$4r=12+8$$

Add 12 and 8 to get 20.

$$4r=20$$

Divide both sides by 4.

$$r=\frac{20}{4}$$

Divide 20 by 4 to get 5.

$$r=5$$
