Question

3/5 (r-7)=1

Please explain step by step on how I solve this problem

Answer 1

r = 8 2/3

Explanation:

3/5 (r-7)=1

3/5 * (r-7)=1

5/3 * 3/5 * (r-7)=1 * 5/3 ==> multiply both sides by 5/3 to remove the 3/5

from the left side of the equation and isolate r

1 * (r-7) = 5/3

r - 7 = 5/3 ==> simplify

r = 7 + 5/3 ==> add 7 on both sides to isolate r

r = 7 + 3/3 + 2/3 ==> simplify

r = 7 + 1 + 2/3

r = 8 + 2/3

r = 8 2/3
