Question

what is the algebraic equation the difference between a number and 11 is 3 more than half the number

Answer 1

Let n = the unknown number

"the difference between a number and 11" translates to n - 11

"3 more than half the number" translates to 1/2n + 3

The word "is" becomes the equal sign.

n - 11 = 1/2n + 3
