Question

What is the result of subtracting the second equation from the first?

- 4x – 2y = -2
X - 2y = 9

Answer 1

-5x + 0y = -11

The y terms are eliminated

Explanation:

- 4x – 2y = -2

X - 2y = 9

We want to subtract the second equation from the first

Distribute a minus sign to all the terms in the second equation

- 4x – 2y = -2

-( x - 2y = 9)

--------------------------

- 4x – 2y = -2

- x + 2y =- 9

------------------------

-5x + 0y = -11

The y terms are eliminated
