The nurse needs to mix 2% solution with 10% solution to get 10 ml of the prescribed 6% solution. what amount of each solution does she need to use?

Volumes of 2% Solution = 5 ml

Volumes of 10% Solution = 5 ml

Simultaneous Linear Equations could be solved by using several methods such as :

If we have two linear equations with 2 variables x and y , then we need to find the value of x and y that satisfying the two equations simultaneously.

Let us tackle the problem!

Let:

Volumes of 2% Solution = x

Volumes of 10% Solution = y

Total Volume = 10 ml

→ Equation 1

The nurse needs to mix 2% solution with 10% solution to get 10 ml of the prescribed 6% solution.

→ Equation 2

Equation 1 - Equation 2:

Volumes of 2% Solution = 5 ml

Volumes of 10% Solution = 5 ml
