 Question 157621This question is from textbook Geometry : I think this is the right category... this is really throwing me off: 2.7(z-7)+6=2.1(3z+1) I'm not sure which step to take first in the order of operations: PEMDAS. Please help me! i need to get this done.This question is from textbook Geometry Answer by checkley77(12569)   (Show Source): You can put this solution on YOUR website!(z-7)+6=2.1(3z+1) First you multiply. z-7=6.2z+2.1 Now combine like terms. z-6.2z=2.1+7 -5.2z=9.1 z=9.1/-5.2 z=-1.75 answer. Proof: -1.75-7=6.2*-1.75+2.1 -8.75=-10.85+2.1 -8.75=-8.75
