Question

What’s the solution of x+y=29 and y=4x-11

Answers

  1. Answer:

    x = 8

    y = 21

    Step-by-step explanation:

    y = 4x − 11

    x + y = 29

    Solve for x:

    x + y = 29

    x + 4x − 11 = 29

    5x − 11 = 29

    5x = 40

    x = 8

    Solve for y:

    y = 4x − 11

    y = 4 × 8 − 11

    y = 21
