Hey there!
We're going to be writing an expression, which means there's no equals sign, and no values are being compared or set equal to each other.
When we say decreased by seven, we really mean you're subtracting seven from that quantity because to decrease is to take away.
Therefore, if we have our number q decreased by seven, we have:
q - 7
Hope this helps!
Answer:

3 - 1 = 2
Hence, The answer would be 2n + 5 = 8
(Hate to be that person, but if it helped, please give me brainliest.)
