3+x(12*4)24
3+x(48)24
51x24
5124=27
48/27
x=1.7?
Not sure if I did the steps correctly.

I 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?

the 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.

3 + x(12*4)  24
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?

no I don't because I was going by pemdas.

what is 'pemdas'?

Parenthesis, Exponents, Multiply, Divide, Add, Subtract (order of operations for evaluating math expressions)

I 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

thank you
