Answer:
Ugh I wish I could help but I'm stuck on the same question algebra sucks.
Step-by-step explanation:
Already you can see that -y and y will make a zero
add both together
3x=21
x=7
plug x in
7+y=5
y=-2
0.49 or .49 because 9.80 / 20 = .49 and .49 * 20 = 9.80
Hope this helped! Lemme know if this is correct, I'm 99.9999999% sure it is XD but if not my apologizes. :)
