The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$7 x = 9 x - 16$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = -16$$
Divide both parts of the equation by -2
We get the answer: x = 8
7*x+5 = 9*x-11
Move free summands (without x)
from left part to right part, we given:
$$7 x = 9 x - 16$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = -16$$
Divide both parts of the equation by -2
x = -16 / (-2)
We get the answer: x = 8
