Hello there!
Let's put these into simpler terms:
-7s + 3s + 2s
10 - 8 - 7
-7s + 3s = -4s
-4s + 2s = 2s
10 - 8 = 2
2 - 7 = -5
We are now left with:
2s - 5, which is your simplified expression.
I hope this helps!

4a + 1v =57
-2a +1v= 9
I will multiply the second by -1 to cancel v variable (elimination method)
4a +1v =57
2a -1v = - 9
add both
6a. = 48
a= 8
4a= 32
32 + v = 57
v= 25
32+25 = 57
-16 +25=9
