(2600 + 6400) - 3 x X = 1200

2p

Answer 1

\(\left(2600+6400\right)-3.X=1200\)

\(9000-3.X=1200\)

\(3.X=9000-1200\)

\(3.X=7800\)

\(X=7800:3\)

\(X=2600\)

Answer 2

(2600+6400)-3xX=1200

⇒ 9000-3xX=1200

⇒ 3xX=9000-1200=7800

⇒ X=7800:3=2600

⇒ X=2600

Answer 3

\(\left(2600+6400\right)-3\times x=1200\)

\(9000-3.x=1200\)

\(3.x=9000-1200\)

\(3.x=7800\)

\(x=7800:3\)

\(x=2600\)
