#x=19#

First, simplify the equation by cross multiplying:

#(x+2)/3=(4x+1)/11#

#(4x+1)*3=(x+2)*11#

Or if you prefer the long way:

#(x+2)/3=(4x+1)/11#

#(x+2)/cancel(3)*cancel(3)=(4x+1)/11*3#
#(x+2)*11=(4x+1)/cancel(11)*3*cancel(11)#
#(4x+1)*3=(x+2)*11#

Then, distribute the coefficients:

#(4x+1)*3=(x+2)*11#

#12x+3=11x+22#

#x=22-3=19#

#x=19#
