Answer :
solve for b.
p=2b+2s
Flip the equation.
2b+2s=p
Add -2s to both sides.
2b+2s+−2s=p+−2s
2b=p−2s
Divide both sides by 2.
2b/2=p−2s/2
b=1/2p−s
p=2b+2s
Flip the equation.
2b+2s=p
Add -2s to both sides.
2b+2s+−2s=p+−2s
2b=p−2s
Divide both sides by 2.
2b/2=p−2s/2
b=1/2p−s
P=2b+2s
-2s -2s
P-2s=2b
