- 180 is the value.
Given that,
[tex]x = 3, y = -6[/tex]
The equation = [tex]36x -[/tex] [tex]8y^2[/tex]
To find the value, we will substitute the given value of [tex]x[/tex] and [tex]y[/tex] in the given equation.
[tex]36x -[/tex] [tex]8y^2[/tex]
[tex]= 36(3) - 8(-6)^2[/tex]
[tex]= 108 - 8(36)[/tex]
[tex]= 108 - 288[/tex]
[tex]= - 180[/tex]
Therefore, -180 is the value.
