Question

if 15x-15equal to 225,then xequalto

Answer 1

Hey,
15x-15=225
15(x-1)=225
x-1=225/15
x-1=15
x=16

Answer 2

$\Huge { \boxed{Answer: }}$


$15x - 15 = 225. \\ \\ transposing \: \: (- 15) \: \: to \: \: RHS: \\ \\ 15x = 225 + 15. \\ 15x = 240. \\ \\ transposing \: \: \times 15 \: \: to \: \: RHS: \\ \\ x = \frac{240}{15} \\ x = 16.$



$\Huge{ \boxed{ \therefore \: \: x = 16}}$
