#x=-38#

Explanation:

First, use cross multiplication to get rid of the fractions

#(x+5)4=(x-6)3#

Next, multiply the integers through to the algebraic expressions.

#4x+20=3x-18#

Next, place terms with #x#'s on one side, and just plain numbers on the other. So, subtracting #3x# from both sides as well as subtracting #20# from both sides gives,

#x=-38#
