$0.25 y - 0.6 = 0.15 y + 3 - 0.8 y$

Step 1

Since $y$ is on the right side of the equation, switch the sides so it is on the left side of the equation.

$0.15 y + 3 - 0.8 y = 0.25 y - 0.6$

Step 2

Subtract $0.8 y$ from $0.15 y$ .

$- 0.65 y + 3 = 0.25 y - 0.6$

Step 3

Move all terms containing $y$ to the left side of the equation.

Step 3.1

Subtract $0.25 y$ from both sides of the equation.

$- 0.65 y + 3 - 0.25 y = - 0.6$

Step 3.2

Subtract $0.25 y$ from $- 0.65 y$ .

$- 0.9 y + 3 = - 0.6$

Step 4

Move all terms not containing $y$ to the right side of the equation.

Step 4.1

Subtract $3$ from both sides of the equation.

$- 0.9 y = - 0.6 - 3$

Step 4.2

Subtract $3$ from $- 0.6$ .

$- 0.9 y = - 3.6$

Step 5

Divide each term in $- 0.9 y = - 3.6$ by $- 0.9$ and simplify.
