9/10 + -x + 3/20 = 3/16
$$\left(\frac{3}{20} - x\right) + \frac{9}{10} = \frac{3}{16}$$
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:
$$- x = - \frac{69}{80}$$
Divide both parts of the equation by -1
We get the answer: x = 69/80
72/80-(x-12/80) = 15/80
Expand brackets in the left part
72/80-x+12/80 = 15/80
Looking for similar summands in the left part:
21/20 - x = 15/80
Move free summands (without x)
from left part to right part, we given:
$$- x = - \frac{69}{80}$$
Divide both parts of the equation by -1
x = -69/80 / (-1)
We get the answer: x = 69/80
