-7*(x - 6)
---------- = 7*(4*x + 6/5)

$$- \frac{7 \left(x - 6\right)}{5} = 7 \left(4 x + \frac{6}{5}\right)$$
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:
$$- \frac{7 x}{5} = 28 x$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-147\right) x}{5} = 0$$
Divide both parts of the equation by -147/5
We get the answer: x = 0
-(7/5)*(x-6) = 7*(4*x+(6/5))
Expand brackets in the left part
-7/5x-6 = 7*(4*x+(6/5))
Expand brackets in the right part
-7/5x-6 = 7*4*x+7*6/5)
Move free summands (without x)
from left part to right part, we given:
$$- \frac{7 x}{5} = 28 x$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-147\right) x}{5} = 0$$
Divide both parts of the equation by -147/5
x = 0 / (-147/5)
We get the answer: x = 0
