Question

Meiling and Meimei divide $69 into 2 shares. 3/4 of Meiling's share is equal to 2/5 of Meimei's share. How much does each get?

Answer 1

L + M = 69
so,
L = 69-M

3/4 (69-M) = 2/5 M
or,
15(69-M) = 8M
1035 - 15M = 8M
23M = 1035
M = 45

So, Meimei had $45
and Meiling had $24

3/4 of 24 = 18
2/5 of 45 = 18

Answer 2

take x as meilings share while take meimei share as y

first equation
x+y=69
now make x or y as the subject so i'll make x as subject so
x=69-y
now we will make an second equation in which we will considey x as(69-y)
second equation
3/4x + 2/5y=69
3/4(39-y)+2/5y=69
39-y+2/5y=92
take 5 as lcm
195-5y
