Step-by-step explanation:
A blood bank needs 6 people to help with a blood drive. 11 people have volunteered. Find how many different groups of 6 can be formed from the 11 volunteers.
First multiply them out to improper fractions 1 3/5 changes into 8/5 and 1 2/5 changes into 7/5 multiply them out and you should get 2 6/25.
X=Y-7
4X+2Y=62
4(Y-7)+2Y=62
4Y-28+2Y=62
6Y=62+28
6Y=90
Y=90/6
Y=15
Larger number^
X=15-7=8
Smaller number^
PROOF:
4*8+2*15=62
32+30=62
62=62
Hope this helps.
