Answer 3

To solve this system of equations, we can use the substitution method. First, we solve one of the equations for one variable in terms of the other variable and substitute that expression into the other equation.

From the first equation, we have:

4 - 2y = 2

Solving for y, we get:

-2y = -2

y = 1

Now we can substitute y = 1 into the second equation and solve for x:

2x + y = 5

2x + 1 = 5

2x = 4

x = 2

Therefore, the solution to the system of equations is (x, y) = (2, 1).

The sum of the solutions is:

2 + 1 = 3

So the answer is 3.
