#6H_3BO_3 -> H_4B_6O_11 + 7H_2O #

Explanation:

There are 6 Boron atoms in the products, so there must be 6 boron atoms on the reactant side, so #6H_6BO_3#.

There are #6 xx 3 = 18# oxygen atoms on the reactant side, so there must be 18 on the product side. There are already 11 in the #H_4B_6O_11# so there are #18 - 11 = 7# left, so there are 7 #H_2O# molecules in the products.

There are #6 xx 3 = 18# hydrogen atoms in the reactants and there are #4 + (7 xx 2) = 18# in the products, so that is balanced.

In the end we have: #18# oxygen atoms in the reactants and #18# in the products #6# boron atoms in the reactants and #6# in the products #18# hydrogen atoms in the reactants and #18# in the products

so the equation is balanced.
