Remember you can do anything to an equation as long as you do it to both sides
x/5-12=48
add 12 to both sides
x/5+12-12=48+12
x/5+0=60
x/5=60
multiply bot sides by 5/1
5x/5=60 times 5
x times 5/5=300
x times 1=300
x=300

Answer:
The answer is 36
Step-by-step explanation:
we know 42 students arrived after the dance started and 78 arrived in total. You have to subtract 42 from 78. how I remember this: part+part=whole whole-part=part
The idea is to shift the number enough so that you can cancel the repeating digits by subtraction.
_____
Example
0.181818_18 multiplied by 100 gives
18.181818_18
Subtracting the original number gives
18.000000_00 . . . . . . all the repeating digits have been eliminated
When you multiply by 100 and subtract 1 times the original, you have multiplied by 99. Thus the value of the original number is 18/99 or 2/11.
