Question

If y =10 and d=5
Then y+d =

Answer 1

In order to do this problem you need to use substitution. Since y=10 and d=5 then you just substitute those values into the equation y+d. Here are the mathematical steps:

Given: y=10, d=5

y+d------original equation

10+5------substitution

15 ------ answer (combine like terms)

If you have any further questions just ask.

Answer 2

Plug in 10 for y, and 5 for d

10 + 5 = 15

15 is your answer
