please i don't know this answer i really need help if i don't pass theses couple of answers i'm gonna stay back please can someone help me please theses are math questions

Answer 1

`b=c/2-3/2a`

Explanation:

Subtracting `3a`:
`2b=c-3a`
dividing by `2`
`b=c/2-3/2a`

Answer 2

`b=(c-3a)/2to(b)`

Explanation:

`"isolate "2b" by subtracting "3a" from both sides"`

`cancel(3a)cancel(-3a)+2b=c-3a`

`2b=c-3a`

`"divide both sides by 2"`

`(cancel(2) b)/cancel(2)=(c-3a)/2`

`b=(c-3a)/2=(-3a+c)/2to(b)`
