Step-by-step explanation:
2x + 2x - 5y - 15 = 0
=> 4x - 5y = 15
three solutions are x = 0, y = - 3
x = 1, y = -11/5, x = 5, y = 1
put y = 0 to and solve for x which gives us the point where the graph cut x - axis
4x - 5×0 = 15
=> x = 15/4 => 3.75
therefore the graph cuts x axis at 3.75 units on the positive side of x axis
