Question

If x equals 3= xequals 4 then use the equation 2x y -6 x equals 18 Z to find the value of y

Answer 1

Greetings!

"If x equals 3 and z equals 4, find the value of y in the equation:
`12xy-6x=18z.`"

Input the value of the variables we were given:

`12(3)y-6(3)=18(4)`
Simplify.

`36y-18=72`
Add 18 to both sides.

`(36y-18)+18=(72)+18`
Simplify.

`36y=90`
Divide both sides by 36.

`(36y)/36=(90)/36`
Simplify.

`y=5/2`

`y=2.5`

The variable, y is equal to 2.5.

Hope this helps.
