Question

Solve the formula for a P=a+b+c

Answer 1

P=a+b+c

Subtracting b and c from both sides.

P-b-c=a+b+c-c

Simplifying both sides.

P-b-c=a

Answer 2

`\huge \boxed{a= P-b-c}`

Explanation:

`P=a+b+c`

Subtracting b and c from both sides.

`P-b-c=a+b+c-b-c`

Simplifying both sides.

`P-b-c=a`
