Question 194799
<font face="Garamond" size="+2">

Since <b><i>y</i></b> is equal to two different things, why not set them equal to each other?


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 4x - 1 = 3x + 5]


Add -3x to both sides, add 1 to both sides:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x = 6]


Then


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y = 4(6) - 1 = 23]


Point of intersection is (6, 23)


{{{drawing(
500, 500, 0, 25, 0, 25,
grid(1),
green(circle(6,23,.2)),
locate(6,23,I(6,23)),
graph(
500, 500, 0, 25, 0, 25,
4x - 1,
3x + 5
))}}}
