Question

Rearrange the equation so b is the independent variable a - 7 = 3 (b+2)

Answer 1

b =
`(1)/(3)`a - 4
`(1)/(3)`

Explanation:

Distribute 3 to the parentheses:

a - 7 = 3(b + 2)

a - 7 = 3b + 6

Subtract 6 from both sides:

a - 13 = 3b

Divide each side by 3:

`(1)/(3)`a - 4
`(1)/(3)` = b

So, the equation rearranged is b =
`(1)/(3)`a - 4
`(1)/(3)`
