Substitution
Solve the system using substitution.
x = y + 2
2y = x - 1
What is (3, 1)?
Solve the system using elimination.
3x + 4y = 31
2x - 4y = -6
What is (5, 4)?
Solve the system by graphing.
y = 2x + 5
y = 4x - 2
Solve the system using substitution.
y = 3x + 5
y = x + 3
What is (-1, 2)?
Solve the system using elimination.
3x + 5y = 54
6x + 4y = 72
What is (8, 6)?
Ethyl paid $34 for two novels and three cookbooks. Gladys paid $36 for three novels and two cookbooks. What is the cost of each type of book? Create a system of linear equations and choose a method to solve.
What is $8 per novel and $6 per cookbook?
Solve the system using substitution.
3x = y + 2
-2y = 1 - 3x
What is (1, 1)?
Solve the system using elimination.
-14x + 9y = 46
14x - 9y = 102
What is no solution?
The sum of two numbers is 14. If one of the numbers is doubled, the sum will become 22. What are the numbers? Create a system of equations and choose a method to solve.
What are 6 and 8?
