1. Without solving, explain why the two linear systems below have the same solution. 4x + 2y = 26 x+y=8 4x + 2y = 26 -2x - 2y = -16​

Answer

The first equation is the same (4x+2y=26), so we only need to compare the second equation. Just by looking at the second equation, you can see that x+y=8 and -2x - 2y = -16 are the same equation because -2 is multiplied to both sides of the equation x+y=8.
