Question

| -4 + 5\2 | - (-x) =-3

Answer 1

Answer:

x = -4.5

Step-by-step explanation:

Solving the equation :

$\left\vert -4+\frac{5}{2} \right\vert -\left( -x\right) =-3$

$\Longleftrightarrow \left\vert \frac{-8}{2} +\frac{5}{2} \right\vert +x =-3$

$\Longleftrightarrow \left\vert \frac{-8+5}{2} \right\vert +x =-3$

$\Longleftrightarrow \left\vert \frac{-3}{2} \right\vert +x =-3$

$\Longleftrightarrow \frac{3}{2} +x =-3$

$\Longleftrightarrow x =-3-\frac{3}{2}$

$\Longleftrightarrow x =-\frac{6}{2} -\frac{3}{2}$

$\Longleftrightarrow x = -(\frac{6}{2} +\frac{3}{2} )$

$\Longleftrightarrow x =-\frac{9}{2}$

$\Longleftrightarrow x =-4.5$
