Question

What is the value of b in the equation b + 8 = 13? a 5 b 8 c 13 d 21

Answer 1

Answer is A because a is the value of the equation

Answer 2

a

Explanation:

b+8=13.

first,you have to make b the subject of the formula (stand alone) and for that to happen +8 will have to cross the equality sign.when a positive sign crosses over the equality sign it changes to a negative sign.

so that would be b=13-8

Therefore,b=5(a)
