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.
