The sum of a number and 11 is 29

a = 18

Step-by-step explanation:

I assume you are trying to find what the first number, a, is. In order to do that, we create a function. When we do that, we get

a + 11 = 29

So, in order to solve for a, we subtract 11 from both sides, getting

a + 11 - 11 = 29 - 11

a = 18

So, we know that the first number, a, is 18, and the second number, is 11.

Answer:18

Step-by-step explanation: take the first ones on each number and add them you get two and 1 + 8 = 9 - 2 + 9 is 29 if that makes sense
