WebTo set them equal, what you need to do is place the equations on either side of an equal sign. (8x-184=4x-148) By doing this, you indicate that the sides are equivalent. Then, you solve for x by, in this example, adding 184 to negative 148. This cancels out the 184 on one side and then you come up with 36 on the right side.
