How many solutions does the following system of equations have? 𝑥 + 𝑦 = −9 −𝑥 − 𝑦 = 9 F. One Solution G. No Solutions H. Infinite Solution

3 answers

One Solution
wrong explain
This system of equations can be simplified to just one equation:

x + y = -9

By adding the two equations together, we get rid of the variable y:

0 = 0

This equation is true for all values of x and y. This means that there are an infinite number of solutions to this system of equations.
