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
