The solution
Detail solution
Given the linear equation:
Move free summands (without a)
from left part to right part, we given:
$$- 9 a = - 10 a - 10$$
Move the summands with the unknown a
from the right part to the left part:
$$a = -10$$
We get the answer: a = -10
-9*a+8 = -10*a-2
Move free summands (without a)
from left part to right part, we given:
$$- 9 a = - 10 a - 10$$
Move the summands with the unknown a
from the right part to the left part:
$$a = -10$$
We get the answer: a = -10
