Question

Solve for w. 4P = 2w - 8b Explain in words or with numbers.

Answer 1

`w=2(P+2b)`

Explanation:

`4P=2w-8b`

Switch sides:

`2w-8b=4P`

Add 8b to both sides:

`\2w-8b+8b=4P+8b`

`2w=4P+8b`

Divide both sides by 2:

`(2w)/(2)=(4P+8b)/(2)`

`w=2P+4b`

Factor out the common factor (2):

`w=2\left(P+2b)`
