Final answer:

To solve the given system of equations 4x + y = 13 and x - y = 2, we can use the method of substitution. Substitute x in terms of y into equation (1) and solve for y. The value of y is 1.

Step-by-step explanation:

To solve the given system of equations:

4x + y = 13 -- (1)

x - y = 2 -- (2)

We can solve this system of equations by using the method of substitution.

From equation (2), we can express x in terms of y: x = 2 + y. Now substitute this value of x into equation (1): 4(2 + y) + y = 13.

Simplify the equation: 8 + 4y + y = 13. Combine like terms: 5y = 5. Divide both sides by 5: y = 1.

Therefore, y = 1.
