Answer 1

\(\frac{x-2}{4}=\frac{5+x}{3}\)

\(\Leftrightarrow3\left(x-2\right)=4\left(5+x\right)\)

\(\Leftrightarrow3x-6=20+4x\)

\(\Leftrightarrow3x-4x=20+6\)

\(\Leftrightarrow-x=26\)

\(\Leftrightarrow x=-26\)

Answer 2

\(\frac{x-2}{4}=\frac{5+x}{3}\)

<=> \(3.\left(x-2\right)=4.\left(x+5\right)\)

<=> \(3x-6=4x+20\)

<=> \(-20-6=4x-3x\)

<=> -26 = x

Answer 3

\(\frac{x-2}{4}=\frac{5+x}{3}\)

\(\Rightarrow3\left(x-2\right)=4\left(x+5\right)\)

\(\Rightarrow3x-6=4x+20\)

\(\Rightarrow4x-3x=-20-6\)

\(\Rightarrow x=-26\)

Answer 4

X - 2/4 = 5 + X / 3

=> X - 2/4 = 5 + X 1/3

=>X x 1/3 = 5 + 2/4

=>

X.( 1 - 1/3 ) - 11/2

=> X = 11/2 : 2/3

=> X = 33/4

Answer 6

         Bài làm :

Ta có :

\(\frac{x-2}{4}=\frac{5+x}{3}\)

\(\Leftrightarrow\left(x-2\right).3=4.\left(5+x\right)\)

\(\Leftrightarrow3x-6=20+4x\)

\(\Leftrightarrow3x-4x=20+6\)

\(\Leftrightarrow x=-26\)

Vậy x=-26

Answer 7

=>(x-2).3=(5+x).4

=>3x-6=20+4x [vì: (x.3)-(2.3)=(5.4)+(x.4)]

=>3x-4x=(20+6)

x=-26

=>> x=-26
