The solution
You have entered
[src]
32*x - 7*x - 32*x - 5 + 35 = 33*x
$$\left(\left(- 32 x + \left(- 7 x + 32 x\right)\right) - 5\right) + 35 = 33 x$$
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = 33 x - 30$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-40\right) x = -30$$
Divide both parts of the equation by -40
We get the answer: x = 3/4
32*x-7*x-32*x-5+35 = 33*x
Looking for similar summands in the left part:
30 - 7*x = 33*x
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = 33 x - 30$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-40\right) x = -30$$
Divide both parts of the equation by -40
x = -30 / (-40)
We get the answer: x = 3/4
