What is the value of x

13

Step-by-step explanation:

We now that the two angles are equal due to them being vertical angles. This way, we can safely set them equal to each other.

4x - 14 = 58

To find what x equals, we first need to get x by itself. That means now we have to add 14 on both sides, leaving us with:

4x = 72

Now we divide 4 on both sides:

x = 13

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
