Answer:
[tex]-\frac{3}{2}[/tex]
Step-by-step explanation:
Let x represent the number.
7 times the number would be [tex]7x[/tex].
5 times the number would be [tex]5x[/tex].
3 less than 5 times the number would be [tex]5x-3[/tex].
Equate both expressions:
[tex]7x=5x-3[/tex]
Let us solve for x.
[tex]7x-5x=5x-5x-3[/tex]
[tex]2x=-3[/tex]
[tex]\frac{2x}{2}=-\frac{3}{2}[/tex]
[tex]x=-\frac{3}{2}[/tex]
Therefore, the required number is [tex]-\frac{3}{2}[/tex].
