Question

I need help with the set up in system of equation form

How do I set this up? one solution containing 20 percent alcohol is mixed with another solution containing 60 percent alcohol to make 10 gallons of a solution that is 32 percent alcohol. How much of each solution is used?

Answer 1

@Hoa

Answer 2

x = amount of 20% alcohol
y = amount of 60% alcohol

eq. 1:
x(20)+y(60)=(x+y)(32)
but
x+y = 10............. x = 10-y
substitute this "y" in equation 1
x(2)+(10-y)(60)=(10)(32)
