Question

Solve for r.
7(r + 1) = 20.3

Answer 1

r = 1.9

Explanation:

7(r + 1) = 20.3

Multiply the parenthesis by 7:

7r + 7 = 20.3

Subtract 7 from each side:

7r = 13.3

Divide 13.3 by 7 to find r:

r = 1.9

Answer 2

r = 1.9

Explanation:

7r + 7 = 20.3

- 7 - 7

7r = 13.3

divide by 7

r = 1.9
