Question

8a+3b=7 solve for b I dont know it.

Answer 1

b =
`(7-8a)/(3)`

Explanation:

8a + 3b = 7 ( subtract 8a from both sides )

3b = 7 - 8a ( isolate b by dividing both sides by 3 )

b =
`(7-8a)/(3)`

Answer 2

`b = (7 - 8a)/(3)`

Explanation:

`8a + 3b = 7`

`3b = 7 - 8a`

`b = (7 - 8a)/(3)`
