Question

If seven less than five times a number is equal to13 more than triple the same number.Choose the equation you will use to solve for the unknown number And the number ( solution)

Answer 1

Let the number be x.

Seven less than 5 times of x is

$5x-7$

!3 more than triple the same number is

$13+3x$

Now,

$\begin{gathered} 13+3x=5x-7 \\ 5x-3x=13+7 \\ 2x=20 \\ x=10 \end{gathered}$

Hence, the number is 10.
