Question

3xsupra5 -  3+x supra 2 = 1 supra 10 . 

Answer 1

3x/5-3+x/2=1/10
2x3x/10-5(3+x)/10=1/10
6x-15-5x=1
x=16

Answer 2

$\frac{3x}{5} - \frac{3+x}{2} = \frac{1}{10}$
$\frac{6x}{10} - \frac{5(3+x)}{10} = \frac{1}{10}$
$\frac{6x - 5(3 + x)}{10} = \frac{1}{10}$
$6x - 5(3 + x) = 1$
$6x - 15 - 5x = 1$
$x = 1 + 15$
$x = 16$
