Question

solve for w in P=2w+2l, if P=38 and l=12

Answer 1

substitute the P for 38 and l for 12 so you have

38 = 2w + 2(12) solve for w

Answer 2

so i take the 2 and 12 and multiply them then subtract them from 38?

Answer 3

that is a good start

Answer 4

okay, thanks :)

Answer 5

38 = 2w + 2(12)

38 = 2w + 24 (replace 2*12 with 24)

38 + -24 = 2w + 24 + -24 (add -24 to both sides)
14 = 2w (simplify both sides)

lost step is divide both sides by 2
