How many gallons of a 20% solution should be mixed with 15 gallon of 70% solution to yield a final mixed of lemonade containing 35% of pure lemonade juice

The correct answer is:  x = 35 gallons

Step-by-step explanation:

We will make equation for this problem:

20 x + 70 · 15 = (x + 15) · 35  => 20 x + 1050 = 35 x + 525 =>

35 x - 20 x = 1050 - 525  =>  15 x = 525 => x = 525/15 = 35 gallons

x = 35 gallons

God with you!!!

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17
