Question

Use the drop-down menus to choose steps in order to correctly solve
1+2b−13=12−4b−2b for b.

Answer 1

2b = 24 - 6b

8b = 24

b = 3

Answer 2

`b=3`

Explanation:

Given equation:

`1+2b-13=12-4b-2b`

Solving for
`b`

Combining like terms on both sides.

`2b+1−13=12-4b-2b`

`2b-12=12-6b`

Adding
`6b` both sides to get
`b` terms on one side.

`2b-12+6b=12-6b+6b`

`8b-12=12`

Adding 12 both sides to isolate
`b` on one side.

`8b-12+12=12+12`

`8b=24`

Dividing both sides by 8.

`(8b)/(8)=(24)/(8)`

∴
`b=3` (Answer)
