9*x - 5 - 7*x + 6 = 13
$$\left(- 7 x + \left(9 x - 5\right)\right) + 6 = 13$$
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$2 x = 12$$
Divide both parts of the equation by 2
We get the answer: x = 6
9*x-5-7*x+6 = 13
Looking for similar summands in the left part:
1 + 2*x = 13
Move free summands (without x)
from left part to right part, we given:
$$2 x = 12$$
Divide both parts of the equation by 2
x = 12 / (2)
We get the answer: x = 6
