If 2x + 5y = 10, how would you write 2 lots of this equation

1. 4x + 10y = 10
2. 4x + 5y = 20
3. 4x + 10y = 20
4. 4x + 5y = 20

If 2x + 5y = 10, how would you write 3 lots of this equation

1. 6x + 15y = 30
2. 6x + 15y = 10
3. 3x + 15y = 10
4. 6x + 5y = 30

If x + 2y = 6, select an equivalent equation from the options below.

1. 3x + 6y = 12
2. 4x + 8y = 24
3. 5x + 2y = 30
4. x + 2y = 3

If 4x + 10y = 18, select an equivalent equation from the options below.

1. 0.4x + 1y = 0.18
2. 4x + y = 1.8
3. 4x + y = 0.18
4. 0.4x + y = 1.8

Given 2x + 3y = 7 and 10x + 15y = 35, explain how we know that they are equivalent fractions.

Drag and drop the terms on the right hand side so that all of the following equations are equivalent to 3x + 4y = 5

TRUE

FALSE

2x + x + 3y + y = 5

4x - x - 3y + y = 5

3y - 4x - y + 1x = 5

3y - 4x + y + 1x = 5

If x + y = 5, rearrange the equation so that we have x = ...

1. x + y = 5
2. x = 5 - y
3. x = 5 + y
4. x = y - 5

If x + 2y = 6, rearrange the equation so that we have x = ...

1. x = 2y - 6
2. x = 6 + 2y
3. x = 6 - 2y
4. x + 2y = 6

If 3 x 6 = 18, select the correct alternatives.

1. 18 ÷ 6 = 3
2. 18 ÷ 3 = 6
3. 18 x 6 = 3
4. 18 x 3 = 6

INSTRUCTIONS - Write down the following notes in your exercise book.

Which of these is not equivalent to
3e - f = 15

1. 3e = 15 + f
2. 3e -f - 15 = 0
3. 3e = f + 15
4. 3e + 15 = f

Which of these is not equivalent to
3e - f = 15

1. 3e = 15 + f
2. 3e -f - 15 = 0
3. 3e = f + 15
4. 3e + 15 = f
