Understanding linear equations in one variable

To "satisfy" an equation means to

• make it true

• simplify it

• repair it

• make it smile

What value makes the equation true? 3x = 36

• x = 12

• x = 5

• x = 13

• x = 7

Which symbol makes the statment below true if x = 18?

2x + 5 ___ 3x - 11

• <

• >

• =

Which equation is balanced with

4 + 6 = 10

• 4 + 6 - 2 = 10 +2

• 4 + 6 +2 = 10 + 2

• 2+ 4 + 6 = 10 - 2

When a number is added to itself, it becomes 24. What is the number?

• 4

• 6

• 8

• 12

If x = 5, then 7 + x = 12.

• True

• False

Determine if each true, false or open. 
12 - 4 = 8

• True
• False
• Open

For what value of x is it the following equation true?
x/3 = 5

• no solution
• 15
• 2
• true for any value

7 - 5 = X

• 5

• 2

• 9

• 12

Is - 5 a solution to x + 5 = 0?

• Yes

• No
