Question

Hello all! Please help me out with this.

I want to find a certain number which I will call Y. It is four times as great as another number which is two less than twenty. What is Y?

Answer 1

Y=72

Explanation:

First we set up the equation which is (20-2) times 4=Y

Then we solve, 20 minus 2 is risk since it is in the parentheses. 20 minus 2 is 18.

After that 18 times 4 is 72

Y=72
