3x-12+5-x=2x-7
2x-7 =2x-7
Means there are infinite solutions.
2x-1=5
2(3)-1=5
6-1=5
5=5
x=3
Set it equal to 260, because thats what they all equal. so then do 260-15 because thats the only price we know, 260-15= 245. then do 245/7=35. each bracelet was 35 dollars. to check do 35*7=245 & 245+15 = 260
