Question

8/6x+2 = x -3
Tìm x

Answer 1

\(\frac{8}{6}x+2=x-3\)

\(\frac{8}{6}x-x=-3-2\)

\(\frac{1}{3}x=-5\)

\(x=-\frac{1}{15}\)

Vậy x= \(-\frac{1}{15}\)

Answer 2

\(\frac{8}{6}\)x+2=x-3

\(\Leftrightarrow\)\(\frac{8}{6}\)x-x=-2-3

\(\Leftrightarrow\)\(\frac{1}{3}\)x=-5​

\(\Leftrightarrow\)x=-5:​\(\frac{1}{3}\)

\(\Leftrightarrow\)x=-15

Vậy x=-15

Answer 3

\(\frac{8}{6}x+2=x-3\\ \frac{8}{6}x-x=-2-3\\ \frac{8}{6}x-x=-5\\ \frac{1}{3}x=-5\\ x=-5:\frac{1}{3}\\ x=-15\)

Answer 4

\(\frac{8}{6x+2}\)=x-3

\(\Rightarrow\)(6x+2)(x-3)=8

\(\Rightarrow\)6x\(^2\)-18x+2x-6=8

\(\Rightarrow\)6x\(^2\)-18x+2x-6-8=0

\(\Rightarrow\)6x\(^2\)-16x-14=0
