X x 18 + X x 2 = 160 X x (18+2) = 160 X x 20 =160 X =160 : 20 X = 80.
x * 18 + x* 2 = 160

Tim x:
2x+2x+2=160
các bn giúp mk nha
x+x+x+x=160.x=?
[x+2]+[x+4]+[x+6]+...+[x+20]=160
[1/2+1/4+1/8+...+1/64]/x=3/8
làm giúp mình nha ai nhanh thì tick
tìm x
a 6 x + 15x8=12.(19-x)
b 160-(35: x +3 )x15=15
c 2x - ( 1309:11-19)-2=0
d (x-7)x(2x-16)=0
giúp mk với
tim x
2 * X * 3 - 160 = 710
giup minh voi duoc ko
tìm x
a,134:(x-3)=35+160:5
b,[(10-x).2+]:3-2=3
tl nhớ kb vs mk na
3 | + | 3 | + … + | 3 | = | |
6 x 8 | 8 x 10 | 158 x 160 |
tìm x
(x+5)+(x+7)+(x+9)+...,........... +(x+15)=160
