Question 613734
Graph y = 5x (shown in green) and y = 4x+6 (shown in blue) to get


{{{ drawing(500, 500, -10, 10, -2, 40,
 graph( 500, 500, -10, 10, -2, 40,0,5x,4x+6)

)}}}


Notice how they cross at the point (6,30). If it's hard to see this, use the "intersect" or "trace" feature on your graphing calculator.



So the solutions are x = 6 and y = 30



Answer: The solution set is { <font color="red">(6,30)</font> }
