Question 470314: This was my original question and it was answered but in what order do you add or does it matter?
"A boy earned $10 more than twice as much as his sister. Together they earned $70. How much did each earn?"
"lets say he paid x for them
then
x-0.85=4.65 solve for x, so add 0.85 to each side
x=5.5
so he paid $5.50 for them"

Hi,

question calls for expressing the amounts each earned in terms of a variable

"A boy earned $10 more than twice as much as his sister...

Let x and (2x+$10) represent the amount the girl and boy made respectively

Question states*** Together they earned $70. 

  x + (2x+$10) = $70

Solving for x

   3x = $60

    x = $20, the amount the girl earned.  the boy earned $50   (2*$20+$10)



CHECKING our Answer***

  $20 + $50 = $70
