Toán Lớp 6: x + 2 = – 10
6 + x = 15
3 + x = 9

  1. x + 2 = -10
    => x = -10 – 2
    => x = -12
    $\text{ Vậy x = -12 }$
    $\text{ ___________ }$
    6 + x = 15
    => x = 15 – 6
    => x = 9
    $\text{ Vậy x = 9 }$
    $\text{ ___________ }$
    3 + x = 9
    => x = 9 – 3
    => x = 6
    $\text{ Vậy x = 6 }$
     

  2. a, $x+2=-10^{}$
    $x= (-10)-2^{}$
    $x=(-10)+(-2)^{}$
    $x=-12^{}$
    b, $6+x=15^{}$
    $x=15-6^{}$
    $x=9^{}$ 
    c, $3+x=9^{}$
    $x=9-3^{}$ 
    $x=6^{}$
    ~ Xin câu trả lời hay nhất ạ ~
