1/4x + 5 = 15
What is x?
1/4x + 5 = 15 subtract 5 form both sides1/4x = 10 multiply both side by 44/4x =40x=40
3.5 or 40
You need 10 to get the 15 you need so what times 1/4=10
Here is how to solve it:1/4x+5=15 -5 -51/4x=15 *4 *4x=40
Gerardo and Klyenewborn have it right. A quarter of 40 is 10, and 10 plus five is 15. The way you solve is:1: subtract five from both sides of the equation2: Multiply both sides of the equation by four. (It's four because you need to get rid of the 1/4)
