Toán Lớp 5: tìm x : (x +128)+(x + 13,6) + ( x + 14,4) + (x-11,3) + (x – 12,1) + (x-12,9 = 1,5×3

Toán Lớp 5: tìm x : (x +128)+(x + 13,6) + ( x + 14,4) + (x-11,3) + (x – 12,1) + (x-12,9 = 1,5×3

  1. $(x +128) + (x + 13,6) + (x + 14,4) + (x – 11,3) + (x – 12,1) + (x – 12,9) = 1,5 × 3$
    $x × 6 + 128 + (13,6 + 14,4) – (12,1 + 12,9) – 11,3 = 4,5$
    $x × 6 + 128 + 28 – 25 – 11,3 = 4,5$
    $x × 6 + 156 – 36,3 = 4,5$
    $x × 6 + 119,7 = 4,5$
    $x × 6 = 4,5 – 119,7$
    $Vì$ $4,5$ $<$ $119,7$ $nên$ $không$ $có$ $x$ $thỏa$ $mãn$ $đề$ $bài$
