1. What is the solution of the system?

− x+ 2y = 4
−4x +y = −5

2. How many solutions does the system have?
−2x +y = 3
4y − 4 =x

3. How many solutions does the system have?
3 x+ y= 5
−2y = 6x − 10

4. How many solutions does the system have?
−x − 2 y= −14
4y = −2x − 12

6. Solve the following system using substitution or elimination.
3x + 3 y= 27
x− 3y = −11

7. Solve the following system using substitution or elimination.
2x + 3y = 9
x+ 5y = 8

the last page i posted was wrong these are the wright questions.
