matt has 6 times as many stickers as david. how many stickers must matt give david How many stickers must Matt give David so that they each will have 175 stickers?
Answer provided by our tutors
Let
x = the number of stickers David has
6x = the number of stickers that Matt has
y = the number of stickers that Matt gives to David
After Matt gives away y stickers he will have 6x - y stickers:
6x - y = 175
After David gets y stickers he will have x + y stickers:
x + y = 175
We have the following system of equations:
6x - y = 175
x + y = 175
