True

200

What is the coefficient and pronumeral of   21h

coefficient = 21

pronumeral = h

 

300

Simplify the following:   10x + 5x – 2x + x

14x

400

Simplify the following:

3 x a x 5 x b

15ab

500

Simplify the following:

16a + 5b - 6a + 3b

16a - 6a + 5b + 3b

10a + 8b

Substitution

100

If x = 2, solve  2x + 3

2 x 2 + 3

= 7

200

If a = 5 and b = 2 solve:   3 + 3a - b

3 + 3 x 5 - 2

3 + 15 - 2

18 - 2

= 16

300

If a = 4, b = 5 and c = 10, solve:    2a + 5b + 2c 

8 + 25 + 10 

= 43

400

If x = 3 and y = -2, solve:   5a + y

15 - 2  

= 13

500

If h = 6 and z = 2, solve: 2(2h + z) - z

2 x (2 x 6 + 2) - 2

2 x (14) - 2 

28 - 2 

24

Write an Equation

100

"The sum of 6 and u"

6 + u

200

"10 less than t"

t - 10

300

"6 slices of oranges shared between y people"

6 / y

400

“the sum of x and 5 is halved”

(x + 5) / 2

500

“the difference between a and 5”

a - 5

One Step Equations

100

Solve for h:

h−3=12

h - 3 + 3 = 12 + 3

h = 15

200

Solve for j:

5j=15

5 x j / 5 = 15 / 5 

j = 3

300

Solve for a:

a/10=4

a / 10 x 10 = 4 x 10

a = 40

400

Solve for i:

i+4=10

i + 4 - 4 = 10 - 4

i = 6

500

Solve for g:

4g + 5 = 13

4 x g + 5 - 5 / 4 = 13 - 5 / 4

g = 2
