Tính nhanh:
a) ( 18 + 29 ) + ( 158 − 18 − 29 ) .
b) ( 13 − 135 + 49 ) − ( 13 + 49 ) .
c) − 326 − ( 115 − 326 ) .
d) 34 . ( − 84 ) + 16 . ( − 34 ) .
Tính nhanh
a, -326 - ( 115- 326)
b, 34. (-84) + 17 . ( -32)
a) -326-(115-326)
b) 34.(-84)+17.(-32)
Giúp mình nha !!!
a) - (30) - (-x) =-|-13|
b) -12 - 4x =20
c) -34 - x =-(-45)
d) -(- x) - 15 = -12
e) -15 - x + 3x = -(-1)
236-4x(35-x)=100
xin giup do
a) 3x + 2 . (-7) = 10
b) 25 -(30 + x) = - (27 - 8)
c) 15 - x = 12 - ( -14)
d) (4x + 11) - ( x + 34) = 67
e) 3 - 17 - x = 289 - (36 + 289)
15x(-236)-235x(-15)
X + -5 = -(-7)
( - 34 ) – x = - ( - 45 )
11 + ( 15 – x ) > 1
15 – x = - ( - 7 )
2( 4x + 1 ) – 1 = 17
–12 + ( x – 9 ) < 0
Help me !
