Which one of the following equations does not have the solution x = 9?

• 4x = 36

• x + 7 = 16

• $\frac{x}{3}=3$

• x + 9 = 0

• 14 − x = 5

The solution to the equation 3a + 8 = 29 is:

• a=21

• $a=12\ \frac{1}{3}$

• a=7

• a=18

• a=3

‘Three less than half a number is the same as four more than the number’ can be expressed as an

equation by:

• $\frac{x}{2}-3=4x\$

• $\frac{x-3}{2}=x+4$

• $\frac{x}{2}-3=x+4$

• $\frac{x}{2}+3=x+4\$

• $\frac{x}{2}-3+4$

When 11 is added to the product of 3 and x, the result is 53. This can be written as:

• 3x + 11 = 53

• 3(x + 11) = 53

• $\frac{x}{3}+11=53$
  

• $\frac{x+11}{3}=53$

• 3x - 11 = 53

Which of the following values of x make the equation 2(x + 4) = 3x true?

• 2

• 4

• 6

• 8

• 10

The equivalent equation that results from subtracting 3 from both sides of 12x - 3 = 27 is:

• 12x = 24

• 12x - 6 = 24

• 12x - 6 = 30

• 9x - 3 = 24

• 12x = 30

To solve 3a + 5 = 17, the first step to apply to both sides is to:

• add 5

• divide by 3

• subtract 17

• divide by 5

• subtract 5
