(y+2)-(3y-4)=-4 equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
(y+2)-(3*y-4) = -4
Expand brackets in the left part
y+2-3*y+4 = -4
Looking for similar summands in the left part:
6 - 2*y = -4
Move free summands (without y)
from left part to right part, we given:
$$- 2 y = -10$$
Divide both parts of the equation by -2
y = -10 / (-2)
We get the answer: y = 5
