Question

A system of linear equations is shown below.

2x – 3y = 17
–3x + y = –1

Choose a method (Elimination or Substitution) to solve the system of equations. Solve and explain your process.

Answer 1

x = -2 and y = -7

Explanation:

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
