Question

A home team's score was 92 points. If you doubled the visiting team's score and subtracted 40, you would also have 92 points. What was the visiting team's score? (Guess and check or a table may work well here.)

Answer 1

Let x=visitor's score. We know that double this score minus 40 is equal to 92, in other words:
\[2x-40=92\]We now need to solve this for x. We'll add 40 to both sides:
\[2x=132\]Finally, divide both sides by 2:
\[x=66\]
