Answer:
Step-by-step explanation:
One antifreeze solution is 26% alcohol and another is 11% alcohol how much of each mixture should be added to make 24 l of a solution that is 21% alcohol?
Let us represent
First solution =>x
Second solution => y
System of equations
x + y = 24.....Equation 1
x = 24 - y
26% × x + 11% × y = 21% × 24
= 0.26x + 0.11y = 5.04... Equation 2
