-5x + 7y = 11 (1)
-5x + 3y = 19 (2) Subtract (2) from (1)
4y = -8 divide both sides by 4
y = -2 (the y-coordinate of the solution point)
Replace -2 for y at one of the given equations, let's say at (2).
-5x +3(-2) = 19
-5x - 6 = 19 add 6 to both sides
-5x = 25 divide both sides by -5
x = -5 (the x-coordinate of the solution point)
Thus, the solution point is (-2, -5).

How do you make a 5 X solution from 10 X stock?
To make a 5X solution from a 10X stock, you can dilute the 10X stock solution by adding an equal volume of diluent (such as water or buffer) to the original solution. For example, if you have 1 mL of the 10X stock solution, you would add 1 mL of diluent to make a 5X solution.
