Answer:
Solving this system of linear equations by elimination we get x=-1 and y=-2
Option 1 is correct option.
Step-by-step explanation:
We are given equations:
We need to solve by Elimination method.
<u>Elimination method:</u> Add or subtract the equations to get an equation in one variable.
Rearranging the equation 1 we get
Add eq(1) and eq(2)
So, after eliminating y we get x=-1
Now finding y by putting x in eq(1)
We get y=-2
So, solving this system of linear equations by elimination we get x=-1 and y=-2
Option 1 is correct option.
