The easiest way to solve this problem is to put (2, -5) into both equations and see if it satisfies/works for both of them. 2 = x and -5 = y.
So for <span>2x + 5y = -19,
</span><span>2(2) + 5(-5) = -19
4 - 25 = -19
-21 </span><span>≠ -19.
You can continue and try it out for </span><span>6y - 8x = -54
6(-5) - 8(2) = -54
-30 - 16 = -54
-46</span> ≠ -54
But since (2, -5) already doesn't work for one equation, it cannot be a solution to the system of equations.

Answer:
3300 Ghana cedis
Step-by-step explanation:
There are 2000 items, so n = 2000
P = 3/4 * 2000 + 1800 = 1500 + 1800 = 3300 Ghana cedis
