Question

The sum of 25/4 and three times a number is equal to 3/4 subtracted from four times the number. find the number

Answer 1

For an instance, n represents the number
$\frac{25}{4}+n=4n- \frac{3}{4}$
$n-4n=-\frac{3}{4}-\frac{25}{4}$
$-3n=-\frac{28}{4}$
$n=-\frac{28}{4} \times -\frac{1}{3}$
$n= \frac{28}{12}$
$n= \frac{7}{3}$

The number is 7/3
