Answer:
The values of x and y to the given equations are x=-1 and
The solution is (-1,)
Step-by-step explanation:
Given equations are
and
to solve the given equations by elimination method :
Adding the given two equations (1) and (2) we get
_______________
4x=-4
Therefore x=-1
Now substitute the value x=-1 in equation(1) we get
(-1)+3y=9
3y=9+1
Therefore the values of x and y to the given equations are x=-1 and
The solution is (-1,)
