3*(y - 5) - 2*(y - 4) = 8
$$3 \left(y - 5\right) - 2 \left(y - 4\right) = 8$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without y)
from left part to right part, we given:
$$y = 15$$
We get the answer: y = 15
3*(y-5)-2*(y-4) = 8
Expand brackets in the left part
3*y-3*5-2*y+2*4 = 8
Looking for similar summands in the left part:
-7 + y = 8
Move free summands (without y)
from left part to right part, we given:
$$y = 15$$
We get the answer: y = 15
