Question 702279: what is two times the sum of a number and seven is eighteen

If I have this correctly, you're asking for:

2 times

the sum of a number and 7

is 18

We can write this as:

2%2A%287%2Bx%29=18 where x is our unknown number.

Then we just need to solve for x:

2%2A%287%2Bx%29=18

14%2B2x=18

2x=4

x=2

From your question, 2 seems like the definite answer because,

two times the sum of seven and two is eighteen, because:

2%2A%287%2B2%29=18 ???

2%2A9=18 ???

18=18 indeed it does

Be careful with the way you ask a question,

because the "what is" at the beginning of your question might be confusing.

I hope this helps! Keep practicing! :)
