Module 9 Test Review

m = 7 and n = 3

m - n

x=4

2x-1

r= -3 and s = 2

r • s

m=3 and n=5

25m - n

a=5 and b=7

3a + b - 2

Solve for y. Enter answer as y=

x = 3y

x + 2y = 20

Solve for x.

y = 6x

2y - 4x = 24

• 2

• 3

• 4

• 6

Solve for y.

x = y - 9

6y + x = 12

• y=2

• y=3

• y=4

• y=6

Solve for x.

y = x + 8

3y + x =20

• x= 1

• x= -1

• x= 2

• x= -2

Solve for y. Enter answer as y= .

x = 6y - 4

2x - 4y = 16
