Question 354035
Let x  be the number of pounds of peanuts.
{{{2.50x+4.75*12=4(x+12)}}} simplify
{{{2.50x+57=4x+48}}} subtract 2.50x from each side, you get
{{{57=4x-2.50x+48}}}
{{{57=1.50x+48}}}  subtract 48 from each side
{{{57-48=1.50x}}}
{{{9=1.50x}}} divide both sides by 1.5
{{{6=x}}} So you need 6 pounds of peanuts.
