Solving Systems using Substitution

2. Evaluate if x = 2 and y = -3
3x + y
5x + 3(x+y) – 2y

3. Solve for x:
3) 3(x-2) = 6
4) 7 – 3(2 + 5x) = 11

4. 5) Solve the system of equations using substitution:
y = 3x
x + 2y = -21

5. 6) Solve the system of equations using substitution:
x+y = -3
y = 2x +6

6. 7) Solve the system of equations using substitution:
-4x + 2y = 6
y = 2x + 3

7. 8) Solve the system of equations:
x + 5y = -3
3x – 2y = 8

8. 9) Solve the system of equations:
2x + y = -4
5x + 3y = -6

9. 10) Solve the system of equations:
a + b = 1
5a + 3b = -1

10. 11) Solve the system of equations:
y = 4x + 2
y= 2x - 8
