2 x 3x-1 = 45
3x-1 = 45 : 2 =24,5
=>Không tồn tại x.
2 . 3x - 1 = 45
3x - 1 = 45 : 2
x = không tồn tại
tim x biet
45-(3x+9)/13=42
(x+1)+(2x+2)+.....+(20x+20)=1050
tim x biet 45-3x+2.{3-x}=4
Tim x: 6^2-(x+3)=45
125-5.(3x-1)=5^5.5^3
4^x+1+4^0=65
70-5.(x-3)=5.3^2
bai 1 tim x biet

Tim x
1) 5x = 120 : 2
2) 3x + 27 = 45
3) 73 + x - 122 = 234 : 2
4) 32 - 2 ( x -1 ) = 12
5) 3 ( x + 1 ) - 15 = 36
6) 21 - ( 4x - 16 ) = 21
7)13 x - 3x = 500
8) 9x + x - 35 = 65
Giup e nha, em can gap
Tim x
-45: (3x - 17) = 3 mu 2
Help me
tim x 1+2+3+...+x=45
tim x 1+2+3+.......+.x= 45
