Tìm \(\Large x\):

a) \(\Large{x \times 2,5 - 3,46 = 4,68}\)

b) \(\Large{x : 1,2 + 2,15 = 7,28}\)

 

• A. a) Đáp án: 3,256
• B. b) Đáp án: 6,156

a) \(\Large{x \times 2,5 - 3,46 = 4,68}\)

    \(\Large{x \times 2,5 = 4,68 + 3,46}\)

    \(\Large{x \times 2,5 = 8,14}\)

    \(\Large{x = 8,14 : 2,5}\)

    \(\Large{x = 3,256}\)

b) \(\Large{x : 1,2 + 2,15 = 7,28}\)

    \(\Large{x : 1,2 = 7,28 - 2,15}\)

    \(\Large{x : 1,2 = 5,13}\)

    \(\Large{x = 5,13 \times 1,2}\)

    \(\Large{x = 6,156}\)
