Question

What is the first step in solving this system with. Elimination Using Multiplication?

Answer 1

Answer:

A. I will eliminate y    B. x = 10   y = -3  

Step-by-step explanation:

  x + 2y = 4

+ x - 2y = 16       Add the equations together

2x = 20              Divide both sides by 2

x = 10

Plug this into the first equation

10 + 2y = 4

-10          -10     Subtract 10 from both sides

2y = -6             Divide both sides by 2

y = -3
