Suppose you add two linear equations that form a system, and you get the result y = −2. how many solutions does the system have?

This system will have 1 solution <==

** if it were to end like 0 = 4, or 2 = -3no variables and numbers that dont equalthis means no solutions.

** if u were to end up with 5 = 5, or -9 = -9...no variables and numbers that do equal, then u will have infinite solutions

** but if u end with y = -2 or x = 5...a variable equaling a number, then u will have 1 solution

It would be 15 m how i got the answer: (20x20) + b^2 = (25x25)400 + b^2 = 625625-400=225square that and get 15hope this : )
