2) The sum of two numbers is 100. Their difference is 4. What are the two numbers?

48 and 52

Step-by-step explanation:

We have a pair of simultaneous equations and will solve these using substitution.

x + y = 100 (1)

x - y = 4 (2)

Solve for x:

x+y=100 , x - y = 4

x=52

Substitute x with 52

(52) + y = 100  , (52) - y = 4

Simplify:

y = 48

hi!

i believe that john has 55 pieces of candy left.

!

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
