Solving a percent mixture problem using a system of linear equations

A chemical company makes two brands of antifreeze.


The first brand is 55% pure antifreeze.


The second brand is 90% antifreeze.


In order to obtain 140 gallons of a mixture that contains 70% pure antifreeze - How many gallons of each antifreeze brand must be used?




Really need help with this.


Thank you,


Stephanie
