Question 1034901
<font color = blue>"Five times a number plus eight equals 28"</font> 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 <font color = blue>Subtract 8 from both sides (to undo the +8)</font>



5*x+0 = 20



5*x = 20



5*x/5 = 20/5 <font color = blue>Divide both sides by 5 (to undo the multiplication of 5)</font>



1*x/1 = 4



1*x = 4



x = 4


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


So to wrap things up, the original sentence translates to the equation <font color=red>5*x+8 = 28</font>


When we solve 5*x+8 = 28 for x, we get <font color=red>x = 4</font>.


So the unknown number is <font color=red>4</font>.
