Step-by-step explanation:

Answer:
The second set of equations is the one you want.
Step-by-step explanation:
If s is the cost of a shirt and you buy 3 of them, you represent that as 3s. Likewise with all the other numbers of articles of clothing you are given. The first situation then is 3s + 5t = 60. The second situation is 2s + 3t = 39.
First,
|-13| represents the absolute value of the number 13. Absolute values cannot be negative. So |-13| cannot become -13, it would become 13.
So,
|-13| - |13| = -13 - 13 = 26 would become
|-13| - |13| = 13 - 13 = 0
Answer:
x = 6.86
Number of video games Fletcher has = 12.58
Step-by-step explanation:
Let
Number of video games Griffin has = x
Number of video games Tommy has = 3x
Number of video games Fletcher has = 3x - 8
Total number of video games is > 40
Griffin + Tommy + Fletcher > 40
x + 3x + (3x - 8) > 40
4x + 3x - 8 > 40
7x > 40 + 8
7x > 48
x > 48 / 7
x > 6.86
Number of video games Fletcher has = 3x - 8
= 3(6.86) - 8
= 20.58 - 8
= 12.58
