# Math Help - help with very small equation

1. ## help with very small equation

i have
.50x+80=.-80x=68

do i need to subract the negative .8x from the .5x or the other way around

or do i need to subract 68 from 80 and get 12
but after i geat 12 i will need to divide by -.30x and my answer will be negative for my problem and it wont make any sense
apreciate any help

2. can you rewrite the equation a bit neater please.

because what im getting from it is:

$

0.50x + 80 = -0.80x = 68
$

... :/

3. ## sorry

i meant to say
.5x + 80 +.-80x =68
what are steps i need to do?

4. Equation:

$
0.5x + 80 - 0.8x = 68
$

Combine Like Terms:

$
80 - 0.3x = 68
$

Move The Constant To The Other Side:

$
-0.3x = -12
$

Divide Through By -0.3:

$
x = 40
$

Understand?
