#### Slide 5 -Quiz

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

#### Slide 6 -Mind map

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

#### Slide 7 -Drag question

A
x + y = 5
B
x = 5 - y
C
x = 5 + y
D
x = y - 5

#### Slide 8 -Quiz

If x + 2y = 6, rearrange the equation so that we have x = ...
A
x = 2y - 6
B
x = 6 + 2y
C
x = 6 - 2y
D
x + 2y = 6

#### Slide 9 -Quiz
