There are several methods to solve a system of equations:
- elimination method
- substitution method
- matrix operations
.
Let's apply the elimination method:
4x-3y=4
2x-y=1
.
Multiply both sides of the second equation be -2 then combine both equations:
4x-3y=4
-4x+2y=-2
----------
-y =2
y=-2
.
Now, you can substitute the above into either equation (I'll pick the second) and solve for x:
2x-y=1
2x-(-2)=1
2x+2=1
2x = -1
x = -1/2
.
Solution: (x,y) = (-1/2, -2)
