The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$7 x = 42$$
Divide both parts of the equation by 7
We get the answer: x = 6
7*x-30 = 12
Move free summands (without x)
from left part to right part, we given:
$$7 x = 42$$
Divide both parts of the equation by 7
x = 42 / (7)
We get the answer: x = 6
