    \[\frac{5x-4}{4x+11}=\frac{13}{11}\] \[\mathrm{Multiply\:by\:LCD=}11\left(4x+11\right)\] \[11\left(5x-4\right)=13\left(4x+11\right)\] \[\mathrm{Expand}\:11\left(5x-4\right):\quad 55x-44\] \[\mathrm{Expand}\:13\left(4x+11\right):\quad 52x+143\] \[55x-44=52x+143\] add 44 on both sides \[55x=52x+187\] subtract 52 on both sides \[3x=187\] divided 3 on both sides x=187/3
