Answer 2

To solve the system of equations:

Equation 1: x + y = 14 Equation 2: x - y = 8

We can solve this system of equations by using the method of elimination or substitution. Let's use the elimination method:

Step 1: Add Equation 1 and Equation 2 to eliminate the variable y:

(x + y) + (x - y) = 14 + 8 x + y + x - y = 22 2x = 22

Step 2: Solve for x:

2x = 22 x = 22/2 x = 11

Step 3: Substitute the value of x back into either Equation 1 or Equation 2 to solve for y. Let's use Equation 1:

x + y = 14 11 + y = 14 y = 14 - 11 y = 3

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