Question

The Sum of 3 and a number is 16

Answer 1

If "the sum of 3 and a number is 16" is given, we can rewrite it as an equation (note that "a number" refers to a variable, commonly x):

3 + x = 16

Now, simply use the Subtraction Property of Equality (subtract 3 from both sides):

3 + x - 3 = 16 - 3

x = 13

Therefore, the number, or x, is equal to 13.

Hope this short response helps! :)
