Find the solution by graphing the equations. 

y=3x+5

y=-2x

(-1, 2)

200

Find the solution by graphing the equations. 

y = 1/2x + 2

y = -2x - 3

(-2, 1)

300

Find the solution by graphing the equations. 

y = -3x + 3

2y = -6x - 10

No solutions

400

Find the solution by graphing the equations. 

y = -x - 4

-x + y = 8

(-6, 2)

500

Find the solution by graphing the equations. 

y = 1/3x + 7

-x + 3y = 21

Infinitely many solutions

Step One Substitution

100

y = 3

y = 4x + 5

(17, 3)

200

y = 2x

y = 3x + 3

(-3, -6)

300

y = 3x + 12

y = 9x - 6

(3, 21)

400

x = -y + 11

x = -4y + 17

(9, 2)

500

x = 5y - 52

x = 4y - 43

(-7, 9)

Step it Up Substitution

100

y = 2

5x + -5y = 30

(8, 2)

200

y = -3x

4x + y = 7

(7, -21)

300

y = 5x + 2

7x - y = 10

(6, 32)

400

6x + 2y = 14

y = 3x + 7

Infinitely many solutions

500

y + 2x = 18

y = -x + 14

(4, 10)

Substitution Star

100

x - y = 11

x - 4y = 29

(5, -6)

200

x + y = 10

2x + 4y = 24

(8, 2)

300

x + 3y = 9

1/3x + y = -3

No solutions

400

x = 6y

x + 7y = 26

(12, 2)

500

y + x = 3

3x = 6y

(2, 1)
