In a rectangular coordinate system, the line $5y = 2x$ intersects the line $3x - 4y = 7$ at point $Z$. What is the sum of the coordinates of point $Z$?

Since the lines intersect, we can set solve for x and y using systems of equations.

 

 

3x=4y+7

 

y=2/5x

 

3x=8/5x+7

 

7/5x=7

 

x=5

 

y=2

 

Thus, (5,2)=5+2=7.
