x-2(3x+2)=16 equation

The teacher will be very surprised to see your correct solution 😉

You have entered [src]

x - 2*(3*x + 2) = 16

$$x - 2 \left(3 x + 2\right) = 16$$

Simplify

Detail solution

Given the linear equation:

x-2*(3*x+2) = 16

Expand brackets in the left part

x-2*3*x-2*2 = 16

Looking for similar summands in the left part:

-4 - 5*x = 16

Move free summands (without x)
from left part to right part, we given:
$$- 5 x = 20$$
Divide both parts of the equation by -5

x = 20 / (-5)

We get the answer: x = -4
