For each ounce of strawberry juice, she uses three times as many ounces of water as juice.

She is making $64$ounces of strawberry infused water.

Let $x$represent the number of ounce of strawberry juice.

And $y$represent the number of ounce of water.

For strawberry infused water, Molly mixes strawberry juice with water

$x+y=64$

For each ounce of strawberry juice, she uses three

times as many ounces of water as juice.

So,$y=3x$

Solve the system of linear equations

$x+y=64$

$y=3x$

Substitute $y=3x$in the first equation,

$x+3x=64$

$4x=64$

Divide both sides of the equation by $4$,

$x=16$

The number of ounce of strawberry juice is$16$ounces.

Substitute $x=16$in the second equation,

$y=3x$

$y=3\left(16\right)$

$y=48$

The number of ounces of water is$48$ounces.

Substitute $x=16$,

$y=48$in the first equation,

$x+y=64$

$16+48=64$

$64=64$

Hence the equation holds true.
