3-x=12

[-10]+x=[-14]

21+x=[-11]

x-[-43]=15

x+[-70]=-43

Answer 1

Answer 2

\(3-x=12\)

\(x=3-12\)

\(x=-9\)

\(\left|-10\right|+x=\left|-14\right|\)

\(10+x=14\)

\(x=14-10\)

\(x=4\)

\(21+x=\left|-11\right|\)

\(21+x=11\)

\(x=11-21\)

\(x=-10\)

\(x-\left|-43\right|=15\)

\(x-43=15\)

\(x=15+43\)

\(x=58\)

\(x+\left|-70\right|=-43\)

\(x+70=-43\)

\(x=-43-70\)

\(x=-113\)

Answer 3

1)  3 - x  = 12 

=> x = 3 - 12 = 3 + ( -12 ) 

=> x = - ( 12- 3 ) = -9

2) (-10) + x = (-14) 

=> x = (-14) - (-10)    => x = (-14) +10  =  -4

3) 21 + x = [-11]  

=> x =  [-11] - 21 = - ( 11 +21 ) 

=> x = -32

4) x - [ - 43 ] = 15

=> x = 15 + [ - 43 ] => x = -(43 - 15 ) 

=> x = -23 

5) x + [-70 ] = -43 

=>  x = -43 + [-70]   => x = -[43 + 70 ]

=> x = -113

tích cho mk nhen !!!

Answer 4

 5) x + (-70) = -43

=> x = -43 - ( -70 ) = -43 + 70 

=> x = 70 - 43 = 27   . Xin lỗi mình làm nhầm !!
