The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
40-12*x = 20-11*x
Move free summands (without x)
from left part to right part, we given:
$$- 12 x = - 11 x - 20$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = -20$$
Divide both parts of the equation by -1
x = -20 / (-1)
We get the answer: x = 20
