Question

solve: 3x+7/4 + 5x-4/7=x+7/2

Answer 1

Answer:

Given equation is,

         $3x+\frac{7}{4} +5x-\frac{4}{7} =x+\frac{7}{2}$

Let's rearrange it.

         $3x+5x-x=\frac{7}{2} -\frac{7}{4} +\frac{4}{7}$    

         $7x=\frac{7}{2} -\frac{7}{4} +\frac{4}{7}$

$LCM =28$

       $7x = \frac{7*14}{28} -\frac{7*7}{28} +\frac{4*4}{28}$

            $= \frac{98-49+16}{28}$

            $=\frac{65}{28}$

         $x= \frac{65}{28*7}$

            $= \frac{65}{196}$

                   Hope it helps you ^_^
