Answer:
The solution to the system of equations is (2, 6)
Explanations:
The given system of equations is:
y = 3x...................(1)
y = x + 4................(2)
Substitute equation (1) into equation (2)
3x = x + 4
3x - x = 4
2x = 4
x = 4/2
x = 2
Substitute x = 2 into equation (1)
y = 3(2)
y = 6
The solution to the system of equations is (2, 6)
