x−10+2=20+10x−10+2=20+10

⇔x−8=30⇔x−8=30

⇔x=30+8⇔x=30+8

⇔x=38

don't talk many

x-10+2=20+10

x-10+2=30

x-10 =30-2

x-10 =28

x=28+10

x=38

We have : x - 10 + 2 = 20 + 10

=> x - 10 + 2 = 30

=> x - 10 = 30 - 2

=> x - 10 = 28

=> x = 28 + 10

=> x = 38

\(x-10+2=20+10\)

\(\Leftrightarrow x-8=30\)

\(\Leftrightarrow x=30+8\)

\(\Leftrightarrow x=38\)

Check my answer, it's shorter than the others people's answer.
