The solution to the system of equation is the point where both lines intersect and it is at (3, 0)
Given the following system of equations
x + y = 3
- 2x + y = -6
Graphically, the point where both lines intersect on the place is the solution to the given system of equation.
From equation 1, x = 3 - y
Substitute into equation 2:
- 2(3-y) + y = -6
-6 + 2y + y = -6
3y = -6 + 6
y = 0
Substitute y = 0 into any of the equation
x + y = 3
x + 0 = 3
x = 3
Hence the solution to the given system of equation is (3, 0)
