The first step is to multiply both side by 8, as this will cancel out the 8 that is beneath the 6-2x. This will then make the equation look like this: 8y = 6-2x. As we are making X the subject of the formula, we should ADD 2x to both sides of the equation, making it look like this: 8y + 2x = 6. To make X the subject of the formula further, we should SUBTRACT 8y from both sides so that 2x is isolated. This will make the equation look like this: 2x = 6 - 8y. The final step, as we want to have X as the subject of the formula, NOT 2x, is divide both of the sides by 2. This means the final equation we are left with, which has x as its subject is x = 3 - 4y.
