Bài 2.Tìm x
a,10+2x=4^5:4^3
b,14x+54=82
c,15x-133=17
7 [ x + 5 ] - 20 = 190 155 - 10 [ x + 1 ]= 55
6 [ x + 2 mũ 3 ] + 40 = 100 15x - 133 = 17
90 [ x + 2 ] = 45 14x + 54= 82
17x - 20 =14
95-5(x+2)=45
14x + 54 =82
15x-133=17
155-10(x+1)=55
các bạn làm đủ hộ nha
1)17-2 (2x-3)=3 2)125-5 (3x-1)=25
3)70-5(2x-3)=45 4)231-(x-6)=133:13
5)2448 : [119- (x-6)]=24 6)15x-13x=882
7)[ (6x-72):2-84].28=5628 8)100-4(30-5x)=20
697/15x+346/x=17
(15x+364):x=697:17(x khác 0)
Tính hợp lý( nếu có thể):
15x( 17- 111)- 17x( 222+ 15).
