Question

1. open ended write an equation with a solution of 25. use the variable x and addition.

Explanation:

Step1: Choose a number to add to x

Let's choose 5 as the number to add to x. So the equation will be in the form \( x + a = b \), where when we solve for x, we get 25.

Step2: Set up the equation

If we let \( x + 5 = 30 \), then to solve for x, we subtract 5 from both sides: \( x = 30 - 5 = 25 \).

Answer:

\( x + 5 = 30 \) (Note: There are many possible answers, for example \( x + 10 = 35 \) would also work as long as when you solve for x, you get 25.)
