Question

2a-5b=10 solve for b

Answer 1

Solve for b means that you need to separate b in one side and the other terms in the other side

2a-5b=10                             subtract 2a from both sides

2a - 5b - 2a = 10 - 2a          combine like terms

- 5b = 10 - 2a                        divide both sides by -5

b = -2 + 2/5 a

I hope that helps!
