$$\frac{\left(4 x + 10\right) - 10}{\frac{174}{5}} = \frac{\left(20 - 2 x\right) + \frac{72}{5}}{\frac{3107}{100}}$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the left part:
Move the summands with the unknown x
from the right part to the left part:
$$\frac{48470 x}{270309} = \frac{3440}{3107}$$
Divide both parts of the equation by 48470/270309
We get the answer: x = 29928/4847
(10+4*x-10)/(174/5) = (20-2*x+(72/5))/(3107/100)
Expand brackets in the left part
10+4*x-10174/5 = (20-2*x+(72/5))/(3107/100)
Expand brackets in the right part
10+4*x-10174/5 = 20-2*x+72/5)/3107/100
Looking for similar summands in the left part:
10*x/87 = 20-2*x+72/5)/3107/100
Move the summands with the unknown x
from the right part to the left part:
$$\frac{48470 x}{270309} = \frac{3440}{3107}$$
Divide both parts of the equation by 48470/270309
x = 3440/3107 / (48470/270309)
We get the answer: x = 29928/4847
