Answer:

x=8 y=11

Explanation:

We can solve this using vertical angles. Vertical angles are a type of proof that two angles are congruent. By this, we can see that 3x-14 = x+2 since they're vertical angles. And that 4y-7=y+11 because they're also vertical angles.

Let's solve the given equations step by step:

Equation 1: 3x - 14 = x + 2

To solve for x, we can start by moving the x term to one side of the equation and the constant terms to the other side:

3x - x = 2 + 14

Simplifying the equation:

2x = 16

Next, we isolate x by dividing both sides of the equation by 2:

2x/2 = 16/2

x = 8

So the solution for Equation 1 is x = 8.

Equation 2: 4y - 7 = y + 11

To solve for y, we'll follow a similar process:

4y - y = 11 + 7

Simplifying the equation:

3y = 18

Dividing both sides of the equation by 3:

3y/3 = 18/3

y = 6

Therefore, the solution for Equation 2 is y = 6.

So the solution to the system of equations is x = 8 and y = 6.
