9*x 18 --- - -- = 2*(x - 9/5) 5 5
$$\frac{9 x}{5} - \frac{18}{5} = 2 \left(x - \frac{9}{5}\right)$$
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:
$$\frac{9 x}{5} = 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-1\right) x}{5} = 0$$
Divide both parts of the equation by -1/5
We get the answer: x = 0
(9/5)*x-(18/5) = 2*(x-(9/5))
Expand brackets in the left part
9/5x-18/5 = 2*(x-(9/5))
Expand brackets in the right part
9/5x-18/5 = 2*x+2*9/5)
Move free summands (without x)
from left part to right part, we given:
$$\frac{9 x}{5} = 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-1\right) x}{5} = 0$$
Divide both parts of the equation by -1/5
x = 0 / (-1/5)
We get the answer: x = 0
