11-x=31 equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- x = 20$$
Divide both parts of the equation by -1
We get the answer: x = -20
11-x = 31
Move free summands (without x)
from left part to right part, we given:
$$- x = 20$$
Divide both parts of the equation by -1
x = 20 / (-1)
We get the answer: x = -20
