An  equation  is formed of two  equal expressions.  The  amount  of  20% milk  and  12% milk  that is needed to be  mixed  is  7.5 gallons  and  12.5 gallons,  respectively.    What is an equation?  An  equation  is formed when two  equal expressions  are equated  together  with the help of an equ al sign '='.     Let the  amount  of  20%milk mixed  be represented by x, while the  amount  of 12% milk mixed is  represented  by y. Therefore, the  two-equation  can be written as,  x+y=20 gallons  0.20x + 0.12y = (0.15×20)  Solve the first equation for x, therefore,  x = 20 - y  substitute the value of x in the second equation,  0.20(20-y) + 0.12y = 3  4 - 0.2y +0.12y = 3  -0.08y = -1  y = 12.5 gallons  substitute the value of y in the first equation,  x + 12.5 = 20  x = 7.5 gallons  Hence, the  amount  of  20% milk  and  12% milk  that is needed to be  mixed  is  7.5 gallons  and  12.5 gallons,  respectively.
