4r+7=10-5r+6
Use the distributive property to multiply 5 by 2-r.
4r+7=16-5r
Add 10 and 6 to get 16.
4r+7+5r=16
Add 5r to both sides.
9r+7=16
Combine 4r and 5r to get 9r.
9r=16-7
Subtract 7 from both sides.
9r=9
Subtract 7 from 16 to get 9.
r=\frac{9}{9}
Divide both sides by 9.
r=1
Divide 9 by 9 to get 1.
