Answer:

b = -n/(2-S) -a

Step-by-step explanation:

S = n/2 (a+b)

divide both sides by (a+b)

S/(a+b) = n/2

flip the equation on the left (it is the same equation just negative)

-(a+b)/-S = n/2

divide both sides by -S

-a-b = n/(2-S)

add a to both sides

-b = n/(2-S) +a

flip the sign (multiply/divide by -1)

b = -n/(2-S) -a
