3 0

1. Put numbers that are on the same group.
3x = 18-15
(3 has x so it is separated from whole numbers 15 and 18)
(15 became negative because you moved it to the other side of the equals sign)

2. Simplify
3x = 18-15
3x = 3

3. Find x
Transfer 3 on 3x to the right side denominator (bottom)
That will make:
x = 3/3

4. Solve
3 divided by 3 is 1

ANSWER: x=1

Jet001 [13]

Yes you do.

The shelf is 24 in. long, so to fit, the total width of all the cases must be < 24 in.

If each case is 3/8 inches:
60 * 3/8 = 22.5

22.5 < 24, therefore they will all fit.
