The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$0 = 10 x + 14$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-10\right) x = 14$$
Divide both parts of the equation by -10
We get the answer: x = -7/5
3-17 = 6*x+4*x
Looking for similar summands in the left part:
-14 = 6*x+4*x
Looking for similar summands in the right part:
-14 = 10*x
Move free summands (without x)
from left part to right part, we given:
$$0 = 10 x + 14$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-10\right) x = 14$$
Divide both parts of the equation by -10
x = 14 / (-10)
We get the answer: x = -7/5
