Translation:I know how to speak many languages and I use them all.
There's a small but meaningful difference between "I can speak many languages" and "I speak many languages." Adding "can" suggests you speak with some fluency/ability.
While we usually translate saber with "know" or "know how," Sometimes "able to" is a reasonable translation. Thus, "I'm able to (can) speak" is meant to capture the idea behind sé hablar.
"Tounges"??? Do you mean "tongues"?
I would say the literal translation is "language". "Tongue" may be a cognate, but in American English, we tend to use "tongue" (as "language) infrequently.
We do say "Speaking in tongues" - but that has a narrow reference and refers to glossolalia.

I entered the same as above, and it came back incorrect with the same but with and underlined. getting really tired of being bounced out of 'test out of level' for really inconsistent, poorly constructed sentences and the cases where the answer is the same as posted yet marked wrong.
I know how to speak many languages and I use them all. Duolingo underlined the "and" and marked it incorrect. This has happened multiple times. Think I'm going to give up on this, if you test through a level, many times you get marked incorrect, report it and it never seems to get fixed. Then you get bounced and no credit for the time you just spent testing through even though the mistakes are Duolingo. I know this is free, but, this is frustrating.
