Answer 3

To solve the system of equations:

1. $x + y = 14$
2. $x - y = 8$

You can use either the substitution method or the elimination method. Let's use the elimination method here.

Step 1: Add both equations to eliminate the y variable. Adding the two equations together: $(x + y) + (x - y) = 14 + 8$

Simplifying the equation: $2x = 22$

Step 2: Solve for $x$: $x = \frac{22}{2}$ $x = 11$

Step 3: Substitute the value of $x$ back into any of the original equations to solve for $y$. Let's use equation 1: $x + y = 14$ $11 + y = 14$

Step 4: Solve for $y$: $y = 14 - 11$ $y = 3$

So, the solution to the system of equations is $x = 11$ and $y = 3$.
