4*x - 1 x + 2 ------- - ----- = 2 9 6
$$- \frac{x + 2}{6} + \frac{4 x - 1}{9} = 2$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$\frac{5 x}{18} = \frac{22}{9}$$
Divide both parts of the equation by 5/18
We get the answer: x = 44/5
(4*x-1)/(9)-(x+2)/(6) = 2
Expand brackets in the left part
4*x-19-x-26 = 2
Looking for similar summands in the left part:
-4/9 + 5*x/18 = 2
Move free summands (without x)
from left part to right part, we given:
$$\frac{5 x}{18} = \frac{22}{9}$$
Divide both parts of the equation by 5/18
x = 22/9 / (5/18)
We get the answer: x = 44/5
