Answer:

r = 0

Step-by-step explanation:

  1. Subtract 28 from each side, so it now looks like this: 0 = 4r
  2. Divide each side by 4, to cancel out the 4 attached to the r. It should now look like this: 0 = r.
  3. 0 remains a 0 because 0 can't be divided.

Therefore, r = 0.

Check to see if it works:

  1. 4 × 0 = 0. This is because anything times 0 is 0.
  2. Plug 0 in: 28 = 0 + 28
  3. 0 + 28 = 28

Therefore, we know 0 is the right answer because as it says in the last step,

0 + 28 is indeed equal to 28, which the problem says is the answer.

Answer: [tex]x=0[/tex]

Flip the equation

[tex]4r+28=28[/tex]

Subtract 28 from both sides

[tex]4r+28-28=28-28\\4r=0[/tex]

Divide both sides by 4

[tex]4r/4=0/4\\x=0[/tex]
