Question 207167
{{{4n+5=6n+7}}}
-----
subtract 4n from both sides of the equation and subtract 7 from both sides of the equation.
you will get:
{{{5 - 7 = 6n - 4n}}}
-----
this becomes:
{{{-2 = 2n}}} which becomes {{{n = -1}}}
-----
to see if this is correct, we substitute in the original equation to get:
{{{(4 * (-1)) + 5 = (6 * (-1)) + 7}}} which becomes:
{{{-4 + 5 = -6 + 7 }}}which becomes:
{{{1 = 1}}} proving that the value of {{{n = -1}}} is good.
