6(-3x-9)=-30 equation

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

You have entered [src]

6*(-3*x - 9) = -30

$$6 \left(- 3 x - 9\right) = -30$$

Simplify

Detail solution

Given the linear equation:

6*(-3*x-9) = -30

Expand brackets in the left part

-6*3*x-6*9 = -30

Move free summands (without x)
from left part to right part, we given:
$$- 18 x = 24$$
Divide both parts of the equation by -18

x = 24 / (-18)

We get the answer: x = -4/3
