Answer:[5, 1]
Step-by-step explanation:
The given system of equations is expressed as
x+y=6 - - - - - - - - -1
x−y=2 - ,- - - - - - - - 2
The first step would be to eliminate y by adding equation 1 to equation 2. It becomes
x + x = 6 + 2
2x = 10
Dividing the left hand side and the right hand side of the equation by 2, it becomes
2x/2 = 10/2
x = 5
Substituting x = 5 into equation 1, it becomes.
5 + y = 6
Subtracting 5 from the left hand side and the right hand side of the equation, it becomes
5 - 5 + y = 6 - 5
y = 1
