Question

10x + 10y = -19
-10x - 10y = 10

Explanation:

Step1: Add the two equations together

The first equation is \(10x + 10y=-19\) and the second is \(-10x - 10y = 10\). When we add them: \((10x + 10y)+(-10x - 10y)=-19 + 10\)

Step2: Simplify the left and right sides

Simplifying the left side: \(10x-10x + 10y-10y=0\). Simplifying the right side: \(-9\). So we get \(0=-9\), which is a contradiction.

Answer:

The system of equations has no solution.
