(1)/(2) - x + (3)/(4) = x - 4

Question

`(1)/(2) - x + (3)/(4) = x - 4`

Answer 1

`x = \frac{21}8`

Explanation:

`~~~~~~~~\frac 1 2 -x + \frac 34 = x-4\\\\\\\implies \frac 24 + \frac 34 - x =x-4\\\\\\\implies \frac 54+4=x+x\\\\\\\implies 2x = (21)/(4)\\\\\\\implies x = (21)/(4 \cdot 2)\\\\\\\implies x = \frac{21}8`
