Dear student 5x+113-12=3x-24⇒25x+11-36=3x-24⇒10x+22-36=3x-24⇒10x+193=3x-22⇒210x+19=33x-2⇒20x+38=9x-6⇒11x=-44⇒x=-4 Regards

5x+11/3 -1/2 =3x-2/4

Dear student

\frac{5 x + 11}{3} - \frac{1}{2} = \frac{3 x - 2}{4} \Rightarrow \frac{2 (5 x + 11) - 3}{6} = \frac{3 x - 2}{4} \Rightarrow \frac{10 x + 22 - 3}{6} = \frac{3 x - 2}{4} \Rightarrow \frac{10 x + 19}{3} = \frac{3 x - 2}{2} \Rightarrow 2 (10 x + 19) = 3 (3 x - 2) \Rightarrow 20 x + 38 = 9 x - 6 \Rightarrow 11 x = - 44 \Rightarrow x = - 4
