You need to get everything related to x on the same side of the equation

Do you know of to factor out the x?

[blissful skiff]

no

[spring stream]

So initially we have x=1.8x+32

Before we start to solve this let's look at smaller problems relevant to the current problem

@blissful skiff
Our first small problem:
Solve 2x=6

Can you solve this?

[blissful skiff]

yeah just divide both sides by 2 thats x =3

[spring stream]

Mhm

now let's say we have the equation
x=8-3x

[spring stream]

Can you transform the equation into this form

Where we have a X term on on side

And a number on the other

[blissful skiff]

yes i first add 3x to both sides and then divide by 4

so x = 2

[spring stream]

Yea

[spring stream]

Now do the same for x=1.8x+32

@blissful skiff

[blissful skiff]

im confused whast the first step

[modern dock]

Can you tell us how you are confused?

What @spring stream is attempting to point out is a parallel between solving x = 8 - 3x and solving x = 1.8x + 32.

The fact that one of the equations features a decimal does not actually matter outside that you need to be prepared to perform some decimal arithmetic.

[blissful skiff]

so i subtract 32 from both sides???

[spring stream]

Alright

Explain how you solved
x=8-3x

Step by step

[blissful skiff]

ok first i swap the equation around so 8-3x = x

and then i add 3x to both sides so 8 = 4x

then i divide both sides by 4 so x = 2

[spring stream]

so now we have x=1.8x+32

Can we subtract anything from both sides

[spring stream]

To get something similar to this

[blissful skiff]

1.8x??????

[spring stream]

Ye

[spring stream]

So what do you get after that

[modern dock]

You are free to do that, but then you need to evaluate whether that step was useful. Subtracting 32 gets you $x - 32 = 1.8x$.

wait remove x from both sides??

so 32=0.8x

then divide both sides by 0.8 so 40=x

x= 40

[spring stream]

Almost

0.8x=-32

x=-40

I'll assume that was a typo

So yea we're done

@blissful skiff

[blissful skiff]

yay

thanks
