Question

**Solve by eliminating the decimal.

Answer 1

I have included a picture with the steps and answer.

Answer 2

I believe this is incorrect.

First..
$\mathrm{Multiply\:both\:sides\:by\:}10 \ \textgreater \ 6.8\cdot \:10-4.2b\cdot \:10=5.6b\cdot \:10-30.2\cdot \:10$

$\mathrm{Refine} \ \textgreater \ 68-42b=56b-302 \ \textgreater \ \mathrm{Subtract\:}68\mathrm{\:from\:both\:sides}$
$68-42b-68=56b-302-68$

$\mathrm{Simplify} \ \textgreater \ -42b=56b-370 \ \textgreater \ \mathrm{Subtract\:}56b\mathrm{\:from\:both\:sides}$
$-42b-56b=56b-370-56b$

$\mathrm{Simplify}\;again \ \textgreater \ -98b=-370 \ \textgreater \ \mathrm{Divide\:both\:sides\:by\:}-98$
$\frac{-98b}{-98}=\frac{-370}{-98} \ \textgreater \ \mathrm{Simplify\;once\;more} \ \textgreater \ b=\frac{185}{49}$

Hope this helps!
