Isolate x on one side of the equation.
15+4x=3x-7
15+4x-4x=3x-7-4x
15=-7-x
15+7=-7+7-x
22=-x
x=-22
In this question it is given that the promoter first purchased 2 3/4 of ads at first. When one of the concerts got cancelled, then the promoter cancels 1 5/8 pages of ads. It is required to be found the number of pages the promoter is using finally.
Number of pages bought by the concert promoter initially = 2 3/4
= 11/4 pages
Number of pages cancelled by the promoter
after one concert got cancelled = 1 5/8
= 13/8 pages
Then the total number of pages finally used by the promoter = (11/4) - (13/8)
= (44 -13)/8
= 31/8
= 3 7/8 pages
So the total amount of space used for ads by the concert promoter is 3 7/8 pages.
