Question

Pls help!!!

1. Solve for w
21+2w=p
Answer will be w=-L+p/2


2. Solve for a
b-2a=c
The answer will be a=c-b/-2 or b-c/2

I know I have the answers but I need the work for it I’ll mark you brainliest

Answer 1

i can help but where’d the L come from in number 1

here 2 though.

b-2a=c
subtract b from both sides which gives you -2a=c-b
divide both sides by -2 to get a alone which gives you a=c-b/-2
