Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.There are two trails near Isaiah's house that he runs regularly, a short loop and a long loop. Last week, he ran 2 short loops and 1 long loop, for a total of 17 kilometers. This week, he ran 5 short loops and 1 long loop, covering a total of 29 kilometers. What is the length of each loop?The short loop has a length of _____ kilometers, and the long loop has a length of _____ kilometers.
Q. Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.There are two trails near Isaiah's house that he runs regularly, a short loop and a long loop. Last week, he ran 2 short loops and 1 long loop, for a total of 17 kilometers. This week, he ran 5 short loops and 1 long loop, covering a total of 29 kilometers. What is the length of each loop?The short loop has a length of _____ kilometers, and the long loop has a length of _____ kilometers.
Define variables: Define the variables for the lengths of the short and long loops.Let x be the length of the short loop in kilometers.Let y be the length of the long loop in kilometers.
Write equations: Write the system of equations based on the given information.First week: 2 short loops and 1 long loop equal 17 kilometers.Second week: 5 short loops and 1 long loop equal 29 kilometers.This gives us the system of equations:2x+y=175x+y=29
Eliminate variable: Decide which variable to eliminate.We can eliminate y by subtracting the first equation from the second equation because they both have the same coefficient for y.
Subtract equations: Subtract the first equation from the second equation to eliminate y and solve for x.(5x+y)−(2x+y)=29−175x+y−2x−y=29−173x=12x=312x=4
Substitute value: Substitute the value of x into one of the original equations to solve for y. Using the first equation: 2x+y=172(4)+y=178+y=17y=17−8y=9
