–3x + y = –1
Choose a method (Elimination or Substitution) to solve the system of equations. Solve and explain your process.
x = -2 and y = -7
If you multiply the second equation by 3, you get -9x + 3y = -3
Then add this to 2x - 3y = 17 and you get -7x = 14; x = -2
Substitute -2 for x into either equation to get the value of y
