2x + 3y = 12

2x - 3y = 12

3x + 2y = 12

x^2 + y^2 = 12

Add 4 to both sides

Replace x with 4

Divide x by 4

Multiply x by 4

To separate variables from constants

To ensure the correct order of operations

To simplify the equation

To make the equation look neat

Subtract 4 from both sides

Multiply 2 by 4

Divide by 2

Add 3 to both sides
