a. 24:(3x-2)=-3
=> 3x-2=24:(-3)
=> 3x-2=-8
=> 3x = -8+2
=> 3x = -6
=> x = -6:3
=> x = -2
b. -45:5.(-3-2x)3???

1/ (2x - 5) +17 =6
2/ 10 - 2(4 - 3x) = - 4
3/- 12 +3(- x + 7) = -18
4/ 24 :(3x - 2)= - 3
5/ - 45 :5.(- 3- 2x) = 3
tìm x
a.(2x-5)+17=6
b.-12+3(-x+7)=-18
c.-45:5.(-3-2x)=3
d.10-2(4-3x)=-4
e.24:(3x-2)=-3
tìm x
12-2(4-3x)=-4
24:(3x-2)=-3
-45:5.(-3-2x)=3
Bài 1:Tìm x
a,(2x-5)+17=6
b,10-2(4-3x)=-4
c,-12+3(-x+7)=18
d,24:(3x-2x)=-3
e,-45:5(-3-2x)=3
Hộ e với ạ.
bài 2 tìm x biết
a)(2x-5)+17=6
b)10-2(4-3x)=-4
c)-12+3(-x+7)=-18
d)24:(3x-2)=-3
e)-45:5.(-3-2x)=3
ai giai mình tich ch
-12 +3(-x + 7)=-18
24:(3x-2) =-3
-45 : 5.(-3 - 2x)= 3
1. 10 - 2 (4 - 3x) = -4
2. -12 + 3 (-x + 7) -18
3. 24 : (3x - 2) = -3
4. -45 : 5 (-3 - 2x) = 3
tìm x:
-12+3(-x+7)=-18
24:(3x-2)=-3
-45:5(-3-2x)=3
1.
a) 2x + 5 = 34 : 32
b) ( 3x - 24 ) . 73 = 2.74
c) [ 3 . ( 42 - x ) + 15 = 23 . 3
d) 126 + ( 132 - x ) = 300
2.
a) 120 - ( x + 55 ) = 60
b) ( 7x - 11)3 = 25 .52 + 200
c) 2x + 2x+4 = 544
3.
a) 10 + 2x = 49 : 47
b) 70 - 5 ( x - 3 ) = 45
c) 4 + 95 : x = 143 : 142 - 23
