Question 126954
{{{2A/3 = 8 + 4A }}}
multiply both sides of the equation by 3
{{{3*(2A/3) = 3*8 + 3*(4A)}}}
{{{2A = 24 + 12A}}}
subtract {{{2A}}} from both sides
{{{2A - 2A = 24 + 12A - 2A}}}
{{{0 = 24 + 10A}}}
subtract 24 from both sides
{{{0 - 24 = 24 - 24 + 10A}}}
{{{-24 = 10A}}}
divide both sides by 10
{{{-(24/10) = A}}}
{{{A = -2.4}}} answer
check answer:
{{{2A/3 = 8 + 4A }}}
{{{2(-2.4)/3 = 8 + 4(-2.4) }}}
{{{-4.8 /3 = 8 - 9.6}}}
{{{-1.6 = -1.6}}}
OK
