Drag each tile to the correct box. Not all tiles will be used Arrange the systems of equations that have a single solution in increasing order of the x-values in their solutions

A. 2x +y = 10
x – 3y = -2

B. x + 2y = 5
2x + y = 4

C. x + 3y = 5
6x – y = 11

D. 2x + y = 10
-6x – 3y = -2

Lin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. she knows that the total cost to download 3 videos was $12. her work to find the equation is shown below. joylin’s work step 1 k= 3/12= 0.25 step 2 y= 0.25x where did joylin make her first error?
