The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$- \frac{9 x}{10} = -63$$
Divide both parts of the equation by -9/10
We get the answer: x = 70
-(9/10)*x+71 = 8
Expand brackets in the left part
-9/10x+71 = 8
Move free summands (without x)
from left part to right part, we given:
$$- \frac{9 x}{10} = -63$$
Divide both parts of the equation by -9/10
x = -63 / (-9/10)
We get the answer: x = 70
