$$\left(- \frac{3 y}{2} + \left(- y + \left(\left(\frac{7 y}{2} + 4 y\right) - 3\right)\right)\right) - 3 = 1$$
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without y)
from left part to right part, we given:
$$5 y = 7$$
Divide both parts of the equation by 5
We get the answer: y = 7/5
4*y+7/2*y-3-y-3/2*y-3 = 1
Looking for similar summands in the left part:
-6 + 5*y = 1
Move free summands (without y)
from left part to right part, we given:
$$5 y = 7$$
Divide both parts of the equation by 5
y = 7 / (5)
We get the answer: y = 7/5
