(40points) 3. Create an equation that meets the following criteria: •Contains the variable on both sides of the equation Uses at least 2 inverse operations to solve to receive full points, you must write out your equation and show ALL the steps to solving it to get the correct solution

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3

This is different from the first one can someone me
