form an equation by adding all the 3 expressions in z together and making it equal to 70

OpenStudy (anonymous):

set all sides equal to 70 so its 4z+5z-3+z+3 then combine like terms and you will get 10z=70 and divide both sides by 10 and you will get z=7 for an answer

@unamericandeli - it would be better if you let mayafrancis do some of the work herself.

@welshfella you're right im sorry @mayafrancis
