Systems of equations

100

y = 3x

70 = x + 2y

x =10

y = 30

substitution

200

x = 2y

70= 2x + 3y

y=10

x=20

this is substitution

300

solve for x and y

y + 3x = 5

-y + 7x = 15

x= 2

y = -1

elimination

400

3x + -4y = 10

7x + 4y = 20

x= 3

y = -1/4

elimination

500

1/2x + 3y =22

6x + - 3y = 30

x = 8

y= 6
