43
8*y - 3 + -5 + 2*y = --
10
$$\left(2 y - 5\right) + \left(8 y - 3\right) = \frac{43}{10}$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the left part:
Move free summands (without y)
from left part to right part, we given:
$$10 y = \frac{123}{10}$$
Divide both parts of the equation by 10
We get the answer: y = 123/100
8*y-3-(5-2*y) = (43/10)
Expand brackets in the left part
8*y-3-5+2*y = (43/10)
Expand brackets in the right part
8*y-3-5+2*y = 43/10
Looking for similar summands in the left part:
-8 + 10*y = 43/10
Move free summands (without y)
from left part to right part, we given:
$$10 y = \frac{123}{10}$$
Divide both parts of the equation by 10
y = 123/10 / (10)
We get the answer: y = 123/100
