"Five times a number plus eight equals 28" means 5*x+8 = 28 where x is the unknown number.


----------------------------------------------------------------


Let's solve for x.


5*x+8 = 28


5*x+8-8 = 28-8 Subtract 8 from both sides (to undo the +8)


5*x+0 = 20


5*x = 20


5*x/5 = 20/5 Divide both sides by 5 (to undo the multiplication of 5)


1*x/1 = 4


1*x = 4


x = 4

----------------------------------------------------------------

So to wrap things up, the original sentence translates to the equation 5*x+8 = 28

When we solve 5*x+8 = 28 for x, we get x = 4.

So the unknown number is 4.
