**The value of 2x + 2y = 10 ** ;
The student is dealing with a system of linear equations and is asked to find the value of 2x + 2y.
The two equations given are:
x + 3y = 1
To find 2x + 2y, let's add these two equations directly:
(3x + y) + (x + 3y) = 19 + 1
4x + 4y = 20
To find the value of 2x + 2y, we simply divide the whole equation by 2:
(4x + 4y) / 2 = 20 / 2
2x + 2y = 10
The value of 2 x + 2 y is 10 after solving the system of equations. The calculations involved finding x and y through substitution. Ultimately, the solution leads us to the required value.
