Question 460572: Part 1:
Solve the following system of equations. Please show your work to receive full credit.
x - y = 19
2x + y = 2
Part 2:
Explain which method you chose to solve the system and why you felt it was the best choice. Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! We could solve by substitution or elimination.
Elimination is the easier and quicker method because we have a +y and -y which would eliminate y.
3x=21
x=7
plug in 7 in the second equation.
14+y=2
y=-12
check
in the first equation
7+12=19
ok
