\(\frac{56-x}{34}=\frac{144}{96}=\frac{3}{2}\)

\(\Rightarrow\left(56-x\right)2=34\cdot3=102\)

\(\Rightarrow56-x=102\div2\)

\(\Rightarrow56-x=51\)

\(\Rightarrow x=56-51\)

\(\Rightarrow x=5\)

\(56-\frac{x}{34}=\frac{144}{96}\)

\(\Rightarrow\frac{x}{34}=56-\frac{144}{96}\)

\(\Rightarrow\frac{x}{34}=\frac{109}{2}\)

\(\Rightarrow2x=109\cdot34=3706\)

\(\Rightarrow x=3706\div2\)

\(\Rightarrow x=1853\)

X/34 = 56 - 144/96

X/34 = 109/2

X/34 = 3706/34

=> X= 3706

X/34 = 56 - 144/96

X/34=109/2

X/34 = 3706/34

=>x=3706

Ta có : 

    56-x/34=144/96

=>     x/34=56-144/96

=>    x/34=109/2

Áp dụng tích chất 2 phân số bằng nhau thì 2 tích chéo bằng nhau ta có:

   x/34=109/2 <=> x.2=34.109

                     => x.2 =3706

                    => x     =3706:2

                   => x      =1853

Vậy x=1853

x là 1853

         x/34 = 56 - 144/96

         x/34 = 109/2

         x/34 = 1853/34

=> x = 1853

\(\frac{56-x}{34}=\frac{144}{96}\)

\(=\frac{56-x}{34}=\frac{3}{2}\)

\(=\frac{56-x}{34}=\frac{51}{34}\)

\(\Rightarrow56-x=51\)

\(=-x=51-56\)

\(\Rightarrow x=5\)

x bang 2

 x= 56 *96 / 34 * 144

x=5376/4896

5 nha e

a) \(96-7\left(x+1\right)=14^4:14^3\)

\(\Rightarrow96-7\left(x+1\right)=14^{4-3}\)

\(\Rightarrow96-7\left(x+1\right)=14\)

\(\Rightarrow7\left(x+1\right)=96-14\)

\(\Rightarrow7\left(x+1\right)=82\)

\(\Rightarrow x+1=\dfrac{82}{7}\)

\(\Rightarrow x=\dfrac{82}{7}-1\)

\(\Rightarrow x=\dfrac{75}{7}\)

b) \(\left(5x+3^4\right)\cdot2^4=2^6\cdot7^2\)

\(\Rightarrow80x+1296=3136\)

\(\Rightarrow80x=1840\)

\(\Rightarrow x=\dfrac{1840}{80}\)

\(\Rightarrow x=23\)

a: =>96-7(x+1)=14
