Answer:
the second one, 3% is very close to 4.5%, while 2,400 is a little less than double 1,250, easy, use logic (don't actually use this answer if this is homework, it might be wrong, this is on the spot and estimation)
Step-by-step explanation:
Sure, post the questions.
3(Y-2) +5Y =Y+22
3Y-6 +5Y=Y+22
3Y -6 +5Y-Y-22=0
3Y+5Y-Y-6-22=0
7Y-28=0
7Y=28
Y=28/7
Y=4
x = - 20 / 3, y = 14 / 3
