The solution
You have entered
[src]
3*x - 37*x - 3*(2*x - 5) = 0
$$\left(- 37 x + 3 x\right) - 3 \left(2 x - 5\right) = 0$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 40 x = -15$$
Divide both parts of the equation by -40
We get the answer: x = 3/8
3*x-37*x-3*(2*x-5) = 0
Expand brackets in the left part
3*x-37*x-3*2*x+3*5 = 0
Looking for similar summands in the left part:
15 - 40*x = 0
Move free summands (without x)
from left part to right part, we given:
$$- 40 x = -15$$
Divide both parts of the equation by -40
x = -15 / (-40)
We get the answer: x = 3/8
