Final answer:

To make x the subject of the equation y = 9 + 3x, you need to isolate x on one side of the equation.

Step-by-step explanation:

To rearrange the equation y = 9 + 3x to make x the subject, we need to isolate x on one side of the equation. Here are the steps:

  1. Subtract 9 from both sides of the equation: y - 9 = 3x
  2. Divide both sides of the equation by 3: (y - 9) / 3 = x
  3. Swap x and (y - 9) to make x the subject: x = (y - 9) / 3

Now the equation is rearranged so that x is the subject.

Step-by-step explanation:

y = 7x - 3

To make x the subject, you need to isolate it. (Get x by itself)

y = 7x - 3

Add 3 on both sides...

y + 3 = 7x

Divide by 7 (Maybe your teacher wants 7x = y = 3 but if she doesn't and wants x completely by itself here's the answer)

x = y/7 + 3/6
