Linear intersections
We found the intersection of this by equalizing both linear equations. Then we separated the numbers with an x variable on one side of the equation; on the other side, we put the numbers alone. Then we simplify each side of the equation. Next, we isolated x to find its value. Finally, we completed again the equation replacing the value of x, to find y.
