Question 498681
Solve for n:
{{{(n+1)/(n+2) = (n-3)/(n+1)}}} Cross-multiply:
{{{(n+1)(n+1) = (n-3)(n+2)}}} Perform the indicated multiplication.
{{{n^2+2n+1 = n^2-n-6}}} Subtract {{{n^2}}} from both sides.
{{{2n+1 = -n-6}}} Add n to both sides.
{{{3n+1 = -6}}} Subtract 1 from both sides.
{{{3n = -7}}} Finally, divide both sides by 3.
{{{highlight(n = -7/3)}}}
