: Solve the following system by using either addition or substution. If a unique solution does not exist, state whethher the system is depent or inconsistent.
10x + 2y = 7
y = -5x + 3 This question is from textbook
You can put this solution on YOUR website! 10x + 2y = 7
y = -5x + 3
Solve this by using substitution since we already have what y equals;
so substitute in the first equation for y: y=-5x+3
10x + 2(-5x+3) = 7
10x - 10x + 6 = 7
6 = 7
so the system is inconsistent
