Question

[I LOVE YOU SO MUCH]

giải các pt:

a)3x-2=2x-3 b)5-(x-6)=4(3-2x) c)\(\dfrac{7x-1}{6}\)+2x=\(\dfrac{16-x}{5}\) d)4(0,5-1,5x)=-\(\dfrac{5x-6}{3}\)

Answer 1

[Nhã Doanh]

a.

3x - 2 = 2x - 3

<=> 3x -2x = -3+2

<=> x = -1

Vậy.............

b.

\(5-\left(x-6\right)=4\left(3-2x\right)\)

\(\Leftrightarrow5-x+6=12-8x\)

\(\Leftrightarrow7x=1\)

\(\Leftrightarrow x=\dfrac{1}{7}\)

Vậy..........
