Answer 3

To solve the system of equations, we'll use the method of substitution or elimination. In this case, let's use the method of elimination.

Given the system of equations:

1. x - 6y = 15
2. x + 6y = 41

Step 1: Add both equations to eliminate the variable y. (1) + (2): (x - 6y) + (x + 6y) = 15 + 41 2x = 56

Step 2: Solve for x: x = 56 / 2 x = 28

Step 3: Substitute the value of x into either of the original equations to find y. Let's use equation (1): x - 6y = 15 28 - 6y = 15

Step 4: Solve for y: -6y = 15 - 28 -6y = -13 y = -13 / -6 y = 13/6 or approximately 2.1667

So, the solution to the system of equations is: x = 28 y = 13/6 or approximately 2.1667
