1)Transitive Property:

This property suggests that if we have three numbers say a,b and c, such that, a=b and b=c then a=c.

Here x=3 and 3=y. Thus x=y by transitive property.

2) Associative Property of Multiplication:

This property suggests that if we have three numbers, say, a,b and c, then the multiplication of these three numbers with each other will yield the same result, irrespective of their order of multiplication.

Thus, a.(b.c)=(a.b).c

For example: 2.(3.4) = (2.3).4

So, here we have, 3.(x.y) = (3.x).y

3) 2x-6=22

⇒2x-6+6=22+6

⇒2x=28

⇒x=28÷2

⇒x=14

Hence, First add 6 both the sides of the equation and then divide by 2. The answer is 14.

⇒c=-6

5) 3x-x+2=12

⇒2x+2=12

⇒2x=12-2

⇒2x=10

⇒x=10÷2

⇒x=5

6) 3(x + 1) + 6 = 33

⇒3x+3+6=33

⇒3x+9=33

⇒3x=33-9

⇒3x=24

⇒x=24÷3

⇒x=8

7) y over negative 2 +5=13

⇒

⇒y =8 ×(-2)

⇒y = -16

10) Fixed amount paid as entry fee by Stephen = $5

Let the number of big water slides taken by Stephen be x.

Charge for each big water slide = $2

Thus, charge for 'x' big water slides = $2 × x = $ 2x

So, total amount paid by Stephen = 5 + 2x

Given, Stephen pays $ 17

Thus, 5+2x=17.

This equation can be used to find out the number of big water slides taken by Stephen.
