The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
-9-4*x+12 = 0
Looking for similar summands in the left part:
3 - 4*x = 0
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = -3$$
Divide both parts of the equation by -4
x = -3 / (-4)
We get the answer: x = 3/4
