tim x biet

Answer 1

\(2(x-5)-3(x+6)=10+x\)

\(\Rightarrow2x-10-3x+18=10x\)

\(\Rightarrow2x-10-3x-18=10+x\)

\(\Rightarrow-x-28=10+x\)

\(\Rightarrow-x-x=10+28\)

\(\Rightarrow-2x=38\)

\(\Rightarrow x=-19\)

Vậy ..

Answer 2

\(2\left(x-5\right)-\left(3x+6\right)=10+x\)

\(\Rightarrow2x-10-3x-18=10+x\)

\(\Rightarrow-x-28=10+x\)

\(\Rightarrow-x=38+x\)

\(\Rightarrow-2x=38\Leftrightarrow x=-19\)
