The solution
Detail solution
Given the linear equation:
Looking for similar summands in the right part:
Move free summands (without a)
from left part to right part, we given:
$$0 = 6 - 7 a$$
Move the summands with the unknown a
from the right part to the left part:
$$7 a = 6$$
Divide both parts of the equation by 7
We get the answer: a = 6/7
0 = -0-7*a+6
Looking for similar summands in the right part:
0 = 6 - 7*a
Move free summands (without a)
from left part to right part, we given:
$$0 = 6 - 7 a$$
Move the summands with the unknown a
from the right part to the left part:
$$7 a = 6$$
Divide both parts of the equation by 7
a = 6 / (7)
We get the answer: a = 6/7
