Answer 2

Answer: Hello there!

"Garrett has one dollar less than three times as much money as Liz has"

If we define G as the amount of money that has Garret and L as the amount of money that Liz has, then:

3L - G = $1

and "together they have $175 "

L + G = $175

Now we want to know how much money Garrett has:

We could isolate L in the second equation:

L = $175 - G

Now we have L written in terms of G, and we can replace it in the first equation.

3L - G = $1

3*($175 - G) - G = $1

$525 - 4G = $1

4G = $525 - $1 = $524

G = $524/4 = $131

So Garret has 131 dollars, and you can replace it in the first equation (or the second) and get how much money Liz has:

$131 +G = $175

G = $175 - $131 = $44
