Question

What is the result of adding these two equations?
- 2x + y = -5
- 2x - 4y = 6

Answer 1

-4x-3y=1

Explanation:

when adding the wo equations, u must add like ters. -2x+-2x is -4x. and positive y+ -y= -3y and-5+6=1. so if u put it all together after adding all integers you get -4x-3y=1

Answer 2

Answer: 5y = -11

Explanation:

-2x + y = -5

(-2x - 4y = 6) -1

-2x + y = -5

2x + 4y = -6

System by elimination method

0 + 5y = -11

5y = -11
