The product of a number and 9, less 20 is 7.

Answer to Problem 9PPS
The required equation is [3x - 3= 48].
Explanation of Solution
Given:
There are 48 soccer teams in the Springtown Association. This is three less than three times the number of teams in the Lyon Association.
Calculation:
Let the number of teams in the Lyon Association is x .
In the sentence ‘Three less than’ means subtract 3 from something.
And ‘Three times the number of teams’ means 3x .
Total soccer teams in Springtown Association are 48.
The equation of the sentence.
“There are 48 soccer teams in the Springtown Association. This is three less than three times the number of teams in the Lyon Association’ is as follows:
3x -3=48.
Hence, the required equation is [3x - 3= 48].
Conclusion:
Hence, the required equation is [3x - 3= 48].
