Question

Solve "18=3 |X-1|" using absolute value​

Answer 1

Answer: $X=-5\quad \mathrm{or}\quad \:X=7$

Step-by-step explanation:

$18=3\left|X-1\right|$

$3\left|X-1\right|=18$

$\frac{3\left|X-1\right|}{3}=\frac{18}{3}$

$\left|X-1\right|=6$

$X-1=-6\quad \mathrm{or}\quad \:X-1=6$

$X=-5\quad \mathrm{or}\quad \:X=7$
