Answer:
3=-8y+5
Step-by-step explanation:
Gather your like terms, - 3y and - 5y which in turn in - 8y. You cant plus by 5 as it is not a like term. IF we were finding y we would rearrange and bring +5 to the other side and so on...
a^2 + b^2 = c^2
65^2 + 34^2 = c^2
4225 + 1156 = c^2
5381 = c^2
c ≈ 73.3552997404
