Solving Systems of Equations

(-1,2)

-4x +5y = 14 y = 3x + 5

(-2,4)

-6x + 2y = 20 y = 6x + 16

(1, -2)

-7x - 2y = -3 y = 4x - 6

(3, 5)

2x - 3y = -9 3x - y = 4

(-3, 6)

3x + y = -3 x=-y+3

No solution

Solve for x and y. -x-y= -4 x+y= 2

(1., 7)

Use elimination to solve the system. x-y= -6 x+ y= 8

(6,-3)

What is the solution to this system of equations. Solve by using substitution. 2x - 3y = 21 y = 3 - x

(8,-2)

What is the solution to this system of equations. Solve by using substitution. x = -4y 3x + 2y = 20

(16,4)

What is the solution to this system of equations. Solve by using substitution. x = 4y 3x - 2y = 40

(-6,1)

What is the solution to this system of equations. Solve by using substitution. x = y - 7 x + 8y = 2

(-2,-4)

What is the solution to this system of equations. Solve by using substitution. y = 2x x + 3y = -14

(1,4)

What is the solution to this system of equations. Solve by using substitution. y = 4x x + y = 5

(-2, -9)

What is the solution to this system of equations. Solve by using substitution. y = 4x -1 y = 2x -5

(3,7)

What is the solution to this system of equations. Solve by using substitution. y = 5x - 8 4x + 3y = 33

(5,8)

What is the solution to this system of equations. Solve by using substitution. y = x + 3 2x + y = 18

(2,1)

What is the solution to this system of equations. Solve by using substitution. y = x -1 x + y = 3

(1, 2)

x + 3y = 7 2x - 4y = -6

(5, 3)

x - 2y = -1 3y = x + 4

(9, 4)

x - 3y = -3 2x + 5y = 38

the lines are parallel

y = -4x +7 8x +2y = -4 What will this look like when graphed?

(-2, -4)

y = 2x 4x - y = -4

One line (these two equations are the same)

y = 3x -11 3x - y = 11 What will this look like when graphed?
