Answer 2

To solve the system of equations:

1. 3x + y = 4
2. 3x - y = 14

We can use the method of elimination or substitution. Let's solve it using the elimination method.

Adding the two equations together eliminates the y term:

(3x + y) + (3x - y) = 4 + 14 6x = 18

Dividing both sides of the equation by 6, we find:

x = 3

Now, substitute the value of x into one of the original equations. Let's use equation 1:

3(3) + y = 4 9 + y = 4

Subtracting 9 from both sides of the equation:

y = 4 - 9 y = -5

Therefore, the solution to the system of equations is x = 3 and y = -5.
