Question

Given the following formula, solve for I.
P =
2(1 + b)

Answer 1

Answer:
`l=(P)/(2)-b`

Explanation:

P = 2(l + b)

Divide both sides by 2:

`(P)/(2)=l+b`

Subtract b from both sides:

`(P)/(2)-b=l`

Note: You can also multiply b by
`(2)/(2)` if you want the left side to be one fraction.

`(P)/(2)-\bigg((2)/(2)\bigg)b=l\\\\\\(P-2b)/(2)=l`
