$7 + 3 y - 5 = 8 y + 11 - 4 y$

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.

$8 y + 11 - 4 y = 7 + 3 y - 5$

Step 2

Subtract $4 y$ from $8 y$ .

$4 y + 11 = 7 + 3 y - 5$

Step 3

Subtract $5$ from $7$ .

$4 y + 11 = 3 y + 2$

Step 4

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