It is : 2X + 5 = 4X +8 2X - 4X = 8 -5 / move over variable to one side , and constants to other, change the sign after moving. -2X = 3 X = -3/2 Jan 14 | Parviz F. Comment
Hi Travina; If I understand correctly, this is NOT... 2x+5=4x=8 But rather... 2x+4=4x=8 Mentally, I can quickly calculate that... 4x=8 x=2 Mentally, I cannot quickly calculate that... 2x+4=8 2x=4 x=2 Mentally, I cannot quickly calculate that... 2x+4=4x 4=2x 2=x Jan 14 | Vivian L. Comment
