Answer :
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
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
