Question

Tìm x biết

a) 3.(x-2)+2.(x-1)=10

b) \(\frac{x+1}{3}=\frac{x-2}{4}\)

Answer 1

b ) x+1:3= x-2:4

     x + 1/3 = x - 1/2

       x= 1/2 - 1/3

     x=1/6

Answer 2

b)3(x-2)+2(x-1)=10

<=>3(x-2)+2(x-1)=5x-8

=>5x-8=10

=>5x=18

=>x=\(\frac{18}{5}\)

Answer 3

a)\(\frac{x+1}{3}=\frac{x-2}{4}\Rightarrow4\left(x+1\right)=3\left(x-2\right)\)

<=>4x+4=3x-6

=>x=-10

Answer 4

-10
