Question

Question 7: Nathan and Kristen are cousins. Nathan is currently four times

Kristen's age. Nathan's age is also 12 more than twice Kristen's age. The
system of equations below models this scenario. What are their current
ages?
x = 4y
x = 12 + 2y

Answer 1

Nathan is 24, Kristen is 6

Explanation:

x=4y --- equation 1

x=12+2y-----equation 2

4y= 12+2y

4y-2y=12

2y=12

y=6

putting the value of y in equation 1 then we get

x=4y

x=4×6

x= 24
