Question

Solve the linear system
x+y=5
x-2y=-1

Find the ratio of the solution’s y-coordinate to its x-coordinate.

Answers

  1. Answer:
    2:3
    Step-by-step explanation:
    x + y = 5      —–>      y = 5 – x
    x – 2y = -1
    x – 2(5 – x) = -1
    x – 10 + 2x = -1
    3x – 10 = -1
    3x = 9
    x = 3
    (3) + y = 5
    y = 2
    Solution to this system: (3,2)
    Ratio of y to x = 2:3
    Hope this helps!
