The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$0 = 3 x - \frac{42}{5}$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = - \frac{42}{5}$$
Divide both parts of the equation by -3
We get the answer: x = 14/5
6 = 3*x-2/2*(12/5)
Expand brackets in the right part
6 = 3*x-2/2*12/5
Move free summands (without x)
from left part to right part, we given:
$$0 = 3 x - \frac{42}{5}$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = - \frac{42}{5}$$
Divide both parts of the equation by -3
x = -42/5 / (-3)
We get the answer: x = 14/5
