Question

Chris is 4 years older than Anna. In 2 years the sum of their ages will be 40. How old is Chris now?

years old

Answer 1

Chris is 20 years old now

Explanation:

Start by making Chris X and Anna X+4 in the equation. Because in 2 years they will be 40, you must add 2 to each person to set the equation equal to 40. Your equation should be (x+2)+(x+6)=40. Combine like terms to get 2x+8=40 and solve for x to get 16. This means Anna is 16 and Chris is 20

Answer 2

Chris is 20 years old
