-(4-y)+2y+1=0 equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
-(4-y)+2*y+1 = 0
Expand brackets in the left part
-4+y+2*y+1 = 0
Looking for similar summands in the left part:
-3 + 3*y = 0
Move free summands (without y)
from left part to right part, we given:
$$3 y = 3$$
Divide both parts of the equation by 3
y = 3 / (3)
We get the answer: y = 1
