Question

Kayla is on level 12 of a new game. Everyday she completes 6 new levels. Maddy is on level 28 of the same game. Everyday she completes 2 new levels.

Write your system to represent where Kayla and Maddy are in the video game

Answer 1

Explanation:

y = 6x + 12

y = 2x + 28

or

l = 6d + 12

l = 2d + 28

Answer 2

Kayla and Maddy will be in the same level in 4 days.

Explanation:

Kayla: y = 6x + 12

Maddy: y = 2x + 28

6x + 12 = 2x + 28

Subtract 2x from both sides;

4x + 12 = 28

Subtract 12 from both sides;

4x = 16

Divide both sides by 4;

x = 4
