A

100

the sum of nine and a number x

9+x

200

Simplify    -4x + y - 6x - 2y

-10x - y

300

4x - 9 = 23

x = 8

400

2(1 + 6x) + 2(3 − 6x) = 7x − 5x

4

500

Find two consecutive integers whose sum is -23

-12 and -11

B

100

Eight less than a number x

x - 8

200

Solve -3x = -18

x = 6

300

-2 (a - 4) + 3 (b + a)

a + 3b + 8

400

4n − 1 = 6n + 8 − 8n + 15

4

500

Find three consecutive integers whose sum is -27

-10, -9, -8

C

100

Simplify 2x + 4x + 5y - 2y

6x + 3y

200

4 - x = 10

x = -6

300

Simplify 3(x - 2) + 7

3x + 1

400

−5(−4r − 6) = 5(6 − r)

0

5x

200

Find the solution of 5x - 2 = 18 if the replacement set is {2,4,6,8,10}

{ 4 }

300

0 = 2x - 4(x+3)

x = -6

400
