Question

need help with this problem asap

Answer 1

Writing this as a variable expression requires us to use a variable if needed.

Heres the answer outright:

X + 72

Heres how we get it:

We get the x from the problem when it says a number but then the problem wants us to modify the variable by 72 and we now we are adding 72 because the problem wants us to "increase" by "72"

So a number, x, is being modified by addition by 72 so we get.

x+72
