$$23 - \frac{23 x}{5} = \frac{18 x}{5} - 19$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$- \frac{23 x}{5} = \frac{18 x}{5} - 42$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-41\right) x}{5} = -42$$
Divide both parts of the equation by -41/5
We get the answer: x = 210/41
23-(23/5)*x = (18/5)*x-19
Expand brackets in the left part
23-23/5x = (18/5)*x-19
Expand brackets in the right part
23-23/5x = 18/5x-19
Move free summands (without x)
from left part to right part, we given:
$$- \frac{23 x}{5} = \frac{18 x}{5} - 42$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-41\right) x}{5} = -42$$
Divide both parts of the equation by -41/5
x = -42 / (-41/5)
We get the answer: x = 210/41
