3+x(48)-24

51x-24

51-24=27

48/27

x=1.7?

Not sure if I did the steps correctly.

**helper**, Friday, January 21, 2011 at 2:43pmI need to see the original problem first to help you.

why did you add 48x + 3 to equal 51x?

then the 'x' is gone in the next line?

**So Lost**, Friday, January 21, 2011 at 3:12pmthe original problem is

3+x(12*4)-24

and I thought because by 12* 4= 48 then by adding 3 that gave me 51 then I subtracted 24 and that left me with 27 so I divided 48 by 27 and that gave me 1.7 so i placed 1.7 as the x and it's on the other line showing how the steps are broken down. I didn't think it would be correct doing it straight across.

if that is the problem then,

3 + 48x - 24

48x - 21

48x = 21

x = 21/48

x = 7/16

you can only combine 'like terms'

x terms can only be added to other x terms, constant terms can only be added to other constant terms.

do you understand?

**helper**, Friday, January 21, 2011 at 4:11pmI followed that

3 + x(12*4) = 24

multiply 12*4

3 + 48x = 24

subtract 3 from both sides

3 - 3 + 48x = 24 - 3

48x = 21

divide both sides by 48

48x/48 = 21/48

x = 21/48

reduce fraction

x = 7/16
