Plug in the values: 2(y)(1)2y=18
First multiply 1 with 2y = 2y(2y)=18
Second multiply 2y and 2y = 4y^2=18
Third divide both sides by 4 = 4y^2/4=18/4
—-> y^2=9/2
Fourth square root both sides = y= √ 9/2 (in square root)
If you need to simplify further you would get 3 √2/2

The simplification of the expression gives y = 3 /√2.

What are equivalent expressions?

Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.

To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.

Given expression;

2zx2 y = 18

where x = 1, z = y

Plug in the values:

2(y)(1)2 y = 18

First multiply 1

2y = 2y(2y)=18

Second multiply by 2y

2y = 4y^2=18

Third divide both sides by 4

= 4y^2/4=18/4

y^2 = 9/2

Fourth square root both sides;

y = √ 9/2

y = 3 /√2
