                                    Algebraic Expressions


Tell whether each algebraic equation is correct.
Write true or not true on the line next to each.
1. a - 6 = 4 , a = 10 _____________

2.
c
12 = 2 , c = 6 _____________


3.
d6
= 3 , d = 18 _____________

4. 8z = 48 , z = 7 _____________


5. x + x + 7 = 16 , x = 4 _____________

6.
30
5 = h , h = 6 _____________


7.
8i
= 1 , i = 8 _____________

8. 13 - z = 8 , z = 4 _____________


If the algebraic expression shown is true, write true on the line. If the algebraic expression is
not true, cross out the value for the variable and write a new value on the line to make it true.
example: a - 1 = 6 , a = 8 ____________
Since this is not true, cross out the 8 and write a = 7 on the line.


9. 9 - w = 1 , w = 9 _____________

10.
p2
= 5 , p = 10 _____________


11.
18
k = 2 , k = 9 _____________

12. 12 + j = 21 , j = 6 _____________


13. 7a = 28 , a = 3 _____________

14.
24
y = 4 , y = 8 _____________


15.
36
6 = b , b = 3 _____________

16. 17 - v = 5 , v = 12 _____________


17. Is this equation in the box to the right always false,
no matter what value you give the variable? 0b = 4
Explain your answer.

1. a - 6 = 4 , a = 10 true

2.

3.

7.
8i

If the algebraic quation shown is true, write true on the line. If the algebraic equation is not
true, cross out the value for the variable and write a new value on the line to make it true.
example: a - 1 = 6 , a = 8 a = 7
Since this is not true, cross out the 8 and write a = 7 on the line.


9. 9 - w = 1 , w = 9 w = 8

10.
p2
= 5 , p = 10 true


11.
18
k = 2 , k = 9 true

12. 12 + j = 21 , j = 6 j = 9


13. 7a = 28 , a = 3 a = 4

14.
24
y = 4 , y = 8 y = 6


15.
36
6 = b , b = 3 b = 6

16. 17 - v = 5 , v = 12 true


17. Is this equation in the box to the right always false,
no matter what value you give the variable? 0b = 4
Explain your answer.
Yes, it is always false. Anything times zero will always equal zero. There is nothing you
can multiply by zero to make 4.
