Solving the first equation:

180/(3x + 6x) = 10
180/(9x) = 10
20/x = 10
x = 2

Plugging x = 2 into the second equation:

10(2) + 2(2) + 62 = 302
20 + 4 + 62 = 302
86 = 302

The second equation is not true, which means there was likely a mistake in solving the first equation. Let's reevaluate:

180/(3x + 6x) = 10
180/(9x) = 10
20/x = 10
x = 2

Plugging x = 2 back into the first equation:

180 / (3(2) + 6(2)) = 10
180 / (6 + 12) = 10
180 / 18 = 10
10 = 10

Therefore, x = 2 is the correct solution for the first equation. Let's check it in the second equation:

10(2) + 2(2) + 62 = 302
20 + 4 + 62 = 302
86 = 302

There was a mistake in the arithmetic in the second equation. Let's correct it:

10(2) + 2(2) + 62 = 302
20 + 4 + 62 = 302
82 = 302

There was another calculation mistake in the second equation. Let's correct it:

10(2) + 2(2) + 62 = 302
20 + 4 + 62 = 302
86 = 302

The corrected equation is 86 = 302, which is incorrect. There seems to be a mistake in the second equation given.
