Answer: b = p - a -c
Step-by-step explanation:
p= a + b + c Solving for b means getting b on one side by itself.
p = a + b + c To solve for b first subtract a from both sides to get,
-b -b
p - a = b + c Now subtract c from both sides to get
-c -c
p - a - c = b
b = p - a -c
3(3-y)+1=31
9-3y+1=31
10-3y=31
-3y=31-10
-3y=21
y=-21/3 = -7
the solution is y=-7
