(4x-6)-(9x-4)=18 equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
(4*x-6)-(9*x-4) = 18
Expand brackets in the left part
4*x-6-9*x+4 = 18
Looking for similar summands in the left part:
-2 - 5*x = 18
Move free summands (without x)
from left part to right part, we given:
−5x=20Divide both parts of the equation by -5
x = 20 / (-5)
We get the answer: x = -4
