Question

I'm having trouble please help me. :( Drake has 150 microphones and each day he gives 10 away to his friends. The number of microphones left, s, if given a function of b, s = 150 - 10b. Solve the equation and determine how many he gave away.

Answer 1

-(s-150)/10

Step-by-step explanation:

To do this we isolate b

First, subtract 150 from both sides

s-150 = -10b

Divide by -10

b = -(s-150)/10
