67x+87x+323x= \frac{6}{7}x+\frac{8}{7}x+3\frac{2}{3}x= 76x+78x+332x=
Let's solve the exercise from left to right.
We will combine the left expression in the following way:
6+87x=147x=2x \frac{6+8}{7}x=\frac{14}{7}x=2x 76+8x=714x=2x
Now we get:
2x+323x=523x 2x+3\frac{2}{3}x=5\frac{2}{3}x 2x+332x=532x
523x 5\frac{2}{3}x 532x
