$? = 361$

We start by distributing the left hand side, letting $? = x$

$12sqrt(36) + 3sqrt(36) - 8sqrt(36) - 2sqrt(36) = sqrt(x) + 11$

$12(6) + 3(6) - 8(6) - 2(6) = sqrt(x) + 11$

$30 = sqrt(x) + 11$

$30 - 11 =sqrt(x)$

$19 = sqrt(x)$

Now, square both sides to get rid of the square root.

$(sqrt(x))^2 = 19^2$

$x = 361$

Hopefully this helps!
