Step 2.1

Add $x$ to both sides of the equation.

$3 x + 4 y - 5 + x = 12 + 5 y$

Step 2.2

Subtract $5 y$ from both sides of the equation.

$3 x + 4 y - 5 + x - 5 y = 12$

Step 2.3

Add $3 x$ and $x$ .

$4 x + 4 y - 5 - 5 y = 12$

Step 2.4

Subtract $5 y$ from $4 y$ .

$4 x - y - 5 = 12$

Step 3

Move all terms not containing a variable to the right side of the equation.
