Answer:
Sum of x and y = 3
Explanations:
The system of equations is:
y = 3x - 1...........(1)
y = -2x + 4........(2)
Equate equations (1) and (2)
3x - 1 = -2x + 4
3x + 2x = 4 + 1
5x = 5
x = 5/5
x = 1
Substitute The value of x into equation (1)
y = 3(1) - 1
y = 3 - 1
y = 2
The sum of x and y:
x + y = 1 + 2
x + y = 3
