Answer:

r = -6/5

Explanation:

1/2r + 6 = 3-2r

Firsly, get all the number without x to one side and number with x to the other side, we got:

Simplify 1/2r to be r/2,

r/2 + 6 =3 - 2r

Multiply both sides by 2:

r + 12 = 6 - 4r

r + 4r = 6 - 12

5r = -6

Divide both side by 5,

r = -6/5

Hope this help you :3
