Greetings!
"If x equals 3 and z equals 4, find the value of y in the equation: [tex]12xy-6x=18z.[/tex]"
Input the value of the variables we were given:
[tex]12(3)y-6(3)=18(4)[/tex]
Simplify.
[tex]36y-18=72[/tex]
Add 18 to both sides.
[tex](36y-18)+18=(72)+18[/tex]
Simplify.
[tex]36y=90[/tex]
Divide both sides by 36.
[tex](36y)/36=(90)/36[/tex]
Simplify.
[tex]y=5/2[/tex]
[tex]y=2.5[/tex]
The variable, y is equal to 2.5.
Hope this helps.
