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:
$$10 x = 97$$
Divide both parts of the equation by 10
We get the answer: x = 97/10
10*(x-9) = 7
Expand brackets in the left part
10*x-10*9 = 7
Move free summands (without x)
from left part to right part, we given:
$$10 x = 97$$
Divide both parts of the equation by 10
x = 97 / (10)
We get the answer: x = 97/10
