Solve by any method x+y=3 , 3y+x=5

PLS SOLVE QUICK

Step-by-step explanation:

label equations

x+y=31

3y+x=52

make x the subject

x=3-y3

subs 3 into 2

3y+3-y=5

2y=2

y=14

subs 4 into 1

x+1=3

x=2

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
