Best ResponseYou've already chosen the best response.00.5z+10=z+4 remember the z on the right has a 1 in front of it, then you just subtract 0.5z from 1z to get 0.5z. 10 = 0.5z +4 Then subtract 4 from 10 which is 6. 10 = 0.5z + 4 4 4 6 = 0.5z Then divide 6 by 0.5 and therefore z = 12 6 = 0.5z /0.5 /0.5 z=12

Best ResponseYou've already chosen the best response.1.05z+10=z+4...put all the z's on one side and all the constants on the other...so subtract a z to each side, and subtract 10 from each side...0.5zz=6...0.5z=6...divide both sides by 0.5 and z=12
