Chapter 2: Q.434 (a),(b),(c) (page 208)

In the following exercises,solve
(a) $|x| = 6$
(b $|- y| = - 3$
(c) $|z| = 0$

Short Answer

Expert verified

The required solutions are

(a) $x = \pm 6$

(b) No Solutions

Step by step solution

(a) STEP 1: Given information

$|x| = 6$

(a) STEP 2: Calculation

The equivalent equations are

$x = - 6 o r x = 6$

$\Rightarrow x = \pm 6$

(b) STEP 1: Given information

$|y| = - 3$

(b) STEP 2: Calculation

No solution, since an absolute value is always positive, there are no solutions to this equation.

(c) STEP 1: Given equation

$|z| = 0$

(c) STEP 2:Calculation

$|z| = 0 z = - 0 o r z = 0 S i n c e - 0 = 0$

So there is only solution
