Answer 1

total - cost of bread and butter = remaining money
100 -7x-9-3x-5= 86-10x ...... is the answer.

Answer 2

Answer:

price of bread = 7x+9

price of butter = 3x-5

Money Lakshmi had = 100 Rs

the amount return to her will be =

100 - ( 7x + 9 + ( 3x - 5 ) )

100-( 7x+3x+9-5 )

100-( 10x + 4 )

100 - 10x - 4

100 - 4 - 10x

96 - 10x
