Question

0.12x-0.54=1.43x-0.76x-3.523

Answer 1

Do you want help solving this or just the answer?

Answer 2

help

Answer 3

i know combine like terms

Answer 4

Well, all you need to do is move the x terms to one side and have everything else on the other. Then you can factor out an x term and divide off the rest

Answer 5

but it never comes out right

Answer 6

Put all the X's on one side, and all the constants on the other. So do:
-0.54+3.523 = 1.43x - 0.76x - 0.12x

and try to go from there

Answer 7

Once you combine all of those terms, then divide everything by the coefficient of X (number in front of x)

Answer 8

but it never comes out right

Answer 9

4.5

Answer 10

Answer 11

???

Answer 12

you should be getting 5.4

Answer 13

Here is a worked solution the your problem, compare it with your notes and see where the trouble lies. I was careful not to skip any steps:

So we have
-0.54+3.523 = 1.43x - 0.76x - 0.12x

2.983 = 1.43x - 0.76x - 0.12x

2.983 = 1.43x - 0.88x

2.983 = 0.55x

2.983 / 0.55 = 0.55x / 0.55

x = 5.423636363636...

Answer 14

DS is faster than me :P

\[0.12x-1.43x+0.76x=-3.523+0.54\]
\[0.12x-1.43x+0.76x=-2.983\]
\[x(0.12-1.43+0.76)=-2.983\]
\[x(0.12-1.43+0.76)=-2.983\]
\[x=(-2.983)/(0.12-1.43+0.76)\]
\[x=(-2.983)/(-0.55)\]
\[x=5.42\]

Answer 16

woah thats alot

Answer 17

Maybe you are missing a negative sign somewhere
