The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
9-4*x = 3*x-40
Move free summands (without x)
from left part to right part, we given:
−4x=3x−49Move the summands with the unknown x
from the right part to the left part:
(−7)x=−49Divide both parts of the equation by -7
x = -49 / (-7)
We get the answer: x = 7
