Question

if a = b/c-b, find the value of b when a = 3 and c = 10.

Answer 1

Question: a=b/c-b when a=3,c=10 find b

Answer: b = 7.5.

Step-by-step explanation: a=b/c-b. a = 3. c = 10. substitute the values, 3 = b/10 - b. 3 ( 10 - b ) = b (10 - b is multiplied as it is sent to LHS as on RHS it is divided) 30 - 3b = b. 30 = 4b (-3b sent to RHS gets added to b and becomes 4b) 4b = 30. b = 7.5.
