$\Rightarrow\underline\bold{{To \: Find}}$

• $Value\:of\:x$

　

　

$\Rightarrow\underline\bold{{Equation}}$

• $9\:-\:3x\:=\:15$

　

　

$\Rightarrow\underline\bold{{Solution}}$

• $9\:-\:3x\:=\:15$

• $-3x\:=\:15\:-\:9$

• $-3x\:=\:6$

• $- x \: = \: \frac{6}{3}$

• $-x\:=\:2$

• $x\:=\:-2$

$\therefore\bold{{Value\:of\:x\:=\:2}}$
