Question

I am trying to remember how to do this.

3 - 7x + 2x when x = 3

When I turn the variables into the given number, do I multiply?

Answer 1

Nope! All you gotta do is insert the numbers. In this case, it's

3-7*3+2*3

The problem stays the same, and in this case, you do need to multiply. But you just replace the variable with the number

Answer 2

So my problem now is 3 - 7 • 3 + 2 • 3? And I do that??

Answer 3

Right? ☺

Answer 4

Yup! :D

Answer 5

Thank you!!!
