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

a ,   x = − 61 x = − 132 b ,   x = − 856 x = − 965

x là 1853

         x/34 = 56 - 144/96

         x/34 = 109/2

         x/34 = 1853/34

=> x = 1853

X/34=56-144/96

x/34=109/2

x=109x34:2=1853

giả giúp mình nhé

Sửa đề xí nha:

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

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

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

\(\Rightarrow\frac{x}{34}=\frac{3706}{34}\Rightarrow x=3706\)

◥ὦɧ◤ŤŔầŃ VăŃ ĤùŃĞ™​ sai đáp số rồi kìa

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

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

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

\(\Rightarrow\frac{x}{34}=\frac{56\cdot2-3}{2}\)

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

\(\Rightarrow2x=109\cdot34\)

\(\Rightarrow2x=3706\)

\(\Rightarrow x=3706:2=1853\)

Vậy x = 1853

a) 5 x 9 + 27 = 45 + 27      b) 96 : 3 - 13 = 32 - 13      c) 56 - 6 x 7 = 56 - 42 

                         = 72                                    = 19                                  = 14

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

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

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

\(\Rightarrow56-x=51\)

\(\Rightarrow x=56-51\)

\(\Rightarrow x=5\)

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

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

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

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

\(\Rightarrow x=3706\div2\)

\(\Rightarrow x=1853\)

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

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

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

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

\(\Rightarrow x=3706\div2=1853\)

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
