Question

If I was asked to think of a number and multiply it by 2, I could write this algebraically as 2x. Write the following algebraically, using x as your unknown. "I think of a number, add 3 to it and multiply the result by 7."​

Answer 1

(x + 3)7

Explanation:

x is a random number that you add three to. you need to do that step first, so you put it in parentheses. outside of it, you put a seven because that means the multiplication of the result from within the parentheses
