Question

7 times a number equals 3 less than 5 times that number. What is the number?

Answer 1

Let the number be N

7N = 5 N - 3

N = -3 / 2

SO YOUR NUMBER IS -3/2

Answer 2

Answer:

$-\frac{3}{2}$

Step-by-step explanation:

Let x represent the number.

7 times the number would be $7x$.

5 times the number would be $5x$.

3 less than 5 times the number would be $5x-3$.

Equate both expressions:

$7x=5x-3$

Let us solve for x.

$7x-5x=5x-5x-3$

$2x=-3$

$\frac{2x}{2}=-\frac{3}{2}$

$x=-\frac{3}{2}$

Therefore, the required number is $-\frac{3}{2}$.
