\(6.\left(5.x+35\right)=330\)
\(5.x+35=330:6\)
\(5.x+35=55\)
\(5.x=55-35\)
\(5.x=20\)
\(x=20:5\)
\(x=4\)
\(6.\left(5.x+35\right)=330\)
\(5.x+35=330:6\)
\(5.x+35=55\)

\(x=20:5\)
\(x=4\)
6.(x+35)=330
6x (5 x X + 35) = 330
Tìm x:
a) 70-5.(2x-3)=45
b) 6.(5.x+35)=330
c)936-(4.x+24)=72
d)(x+1)+(x+3)+(x+5)=30
e)(x+2)+(x+4)+(x+6)+.....+(x+100)=2650
tìm x
70-5 .(2x-3) =45
156 -(x cộng 61 ) =82
6.(5x cộng 35) =330
936- (4x cộng 24) =72
6 . ( 5x + 35 ) = 330
Bài 6: Tìm X biết :
a) X : [(1800+600) :30] = 560 : (315-35)
b) [(250-50) : 15] : X = (450-60) :130
c) (158- X) : 7 = 20
d) 231-(X - 6) = 1339:13
e) 70-5 (2xX-3) = 45
f)156 - (x +61) = 82
g) 6x(5xX+35) = 330
h) 936 - (4xX +24) =72
a) 70-5 (2x-3)=45
b) 6(5x+35)=330
c)936-(4x+24)=72
d)5(3x+34)=515
6. (5x + 35)=330
Chỉ 1 câu thôi các bạn giúp mình nha mình đang cần gấp
a) 1+3+5+7+..........+x=25
b) 2+4+6+...........+x=60
c) 1+4+7+10+.........+x=330
