Make 2 equations from the question first

x is the number of pints for type 1

y is the number of pints for type 2

The equation

x + y = 120

60% x + 85% y = 65% (x + y)

Solve the equation

From the 2nd equation

0.6x + 0.85y = 0.65 (x + y)

0.6x + 0.85y = 0.65x + 0.65y

0.85y - 0.65y = 0.65x - 0.6x

0.2y = 0.05x

y = 4x

From the 1st equation

x + y = 120

x + 4x = 120

5x = 120

x = 24

y = 4x

y = 96

The first type should be 24 pints, the second type should be 96 pints
