Solve for b:
-3 = b+2/5
Put each term in b+2/5 over the common denominator 5: b+2/5 = (5 b)/5+2/5:
-3 = (5 b)/5+2/5
(5 b)/5+2/5 = (5 b+2)/5:
-3 = (5 b+2)/5
-3 = (5 b+2)/5 is equivalent to (5 b+2)/5 = -3:
(5 b+2)/5 = -3
Multiply both sides of (5 b+2)/5 = -3 by 5:
(5 (5 b+2))/5 = -3×5
(5 (5 b+2))/5 = 5/5×(5 b+2) = 5 b+2:
5 b+2 = -3×5
5 (-3) = -15:
Answer: |
| 5 b+2 = -15 b = -17/5
