Answer: one solution x=3
Explanation:
this problem is very simple, we need to figure out out what number(x) when multiplied by 2, and then you minus 3 (2x-3)
we need to then multiply this number by 5 to get 15, so 5x3 is what we need to find, so then we need to have the number 6 as 2x, or 3 as x.
so we end up with equation 5(2*3-3) or, 5(6-3), which equals 5*3= 15.
