đúng nha! lp 6 trở lên ms lm đc thui !
\(x+12=3\)
\(x=3-12\)
\(x=-9\)
\(x+43=67\)
\(x=67-43\)
\(x=24\)
\(x+23=67\)
\(x=67-23\)
\(x=44\)
Tìm x:
x + 12 = 3 x + 43 = 67 x + 23 = 67
x = 3 - 12 x = 67 - 43 x = 67 - 23
x = -9 x = 24 x = 44
x+12=3
x=3-12
x=-9
x+43=67
x=67-43
x=24
x+23=67
x=67-23
x=44
bn hok tốt nạ!
1)x + 12 = 3
x = 3 - 12
x = - 9
Vậy x = -9
2) x + 43 = 67
x = 67 - 43
x = 24
Vậy x = 24
3) x + 23 = 67
x = 67 - 23
x = 44
Vậy x = 44
x+12=3
=> x = -9
x+43=67
=> x = 24
x+23=67
=> x = 44
:)

Đúng thì k cho mk
