The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without a)
from left part to right part, we given:
$$7 a = -22$$
Divide both parts of the equation by 7
We get the answer: a = -22/7
7*(a+6) = 20
Expand brackets in the left part
7*a+7*6 = 20
Move free summands (without a)
from left part to right part, we given:
$$7 a = -22$$
Divide both parts of the equation by 7
a = -22 / (7)
We get the answer: a = -22/7
