See the entire solution process below:

First, group like terms:

$7 \sqrt{x} - \sqrt{x} + 3 \sqrt{y} - 3 \sqrt{y}$ $7sqrt(x) - sqrt(x) + 3sqrt(y) - 3sqrt(y)$

Now, combine like terms:

$7 \sqrt{x} - 1 \sqrt{x} + 3 \sqrt{y} - 3 \sqrt{y}$ $7sqrt(x) - 1sqrt(x) + 3sqrt(y) - 3sqrt(y)$

$(7 - 1) \sqrt{x} + (3 - 3) \sqrt{y}$ $(7 - 1)sqrt(x) + (3 - 3)sqrt(y)$

$6 \sqrt{x} + 0 \sqrt{y}$ $6sqrt(x) + 0sqrt(y)$

$6 \sqrt{x}$ $6sqrt(x)$
