Answer:
Step-by-step explanation:
Okay, so you need to get b alone. You can subtract 10 from 7. You get -3. The equation is now -3 = 5/8b. To get rid of a fraction, you can multiply by the denominator. So multiply both sides by 8.
The equation is now -24 = 5b. Divide both sides by 5.
The answer is -4.8.
