The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
3*x-6*(4*x+3) = 10
Expand brackets in the left part
3*x-6*4*x-6*3 = 10
Looking for similar summands in the left part:
-18 - 21*x = 10
Move free summands (without x)
from left part to right part, we given:
$$- 21 x = 28$$
Divide both parts of the equation by -21
x = 28 / (-21)
We get the answer: x = -4/3
