Question

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

Answer 1

x = -4.5

Explanation:

Solving the equation :

`\left\vert -4+(5)/(2) \right\vert -\left( -x\right) =-3`

`\Longleftrightarrow \left\vert (-8)/(2) +(5)/(2) \right\vert +x =-3`

`\Longleftrightarrow \left\vert (-8+5)/(2) \right\vert +x =-3`

`\Longleftrightarrow \left\vert (-3)/(2) \right\vert +x =-3`

`\Longleftrightarrow (3)/(2) +x =-3`

`\Longleftrightarrow x =-3-(3)/(2)`

`\Longleftrightarrow x =-(6)/(2) -(3)/(2)`

`\Longleftrightarrow x = -((6)/(2) +(3)/(2) )`

`\Longleftrightarrow x =-(9)/(2)`

`\Longleftrightarrow x =-4.5`
