Question 174564
not quite sure what those 5 steps are so since you have access to what the book says about the 5 steps hopefully you can work those five steps from this solution:
:
lets call call the unknown number x
:
one third of x = 5 less (subtraction from) 1/2 of x
:
1/3(x)=1/2(x)-5
:
multiply all terms by Least common multiple of 6
:
2x=3x-30....subtract 3x from both sides
:
-x=-30.....divide by -1 on both sides
:
{{{highlight(x=30)}}}
:
checking:
1/3(30)=1/2(30)-5
:
10=15-5
:
10=10......checked
