17x + 4x = 86 : 86 + 20160
21x = 1+ 1
21x = 2
x = 2 : 21
x = \(\frac{2}{21}\)
TL : 17x\(\frac{2}{21}\)+ 4 x \(\frac{2}{21}\)= 86: 86 + (2016)0

17x - 4x = 8^2 + 1
(17 - 4 )x = 64 + 1
13x = 65
x = 65 : 13
x = 5

17x - 4x = 88:86+(2016)0
<=> 82 + 1 = 13x
<=> 65 = 13x
<=> x = 5
\(17x-4x=8^8:8^6+\left(2016\right)^0\)
\(\Rightarrow13x=8^2+1\)
\(\Rightarrow13x=65\)
\(\Rightarrow x=5\)
Vậy \(x=5\)

17x – 4x = 88: 86 + (2016)0 13x = 82 + 1 = 64 + 1 = 65 x = 65:13 = 5 x = 5 |
17x – 4x = 88: 86 + (2016)0 13x = 82 + 1 = 64 + 1 = 65 x = 65:13 = 5 x = 5 |

Bài làm
17x - 4x = 88 : 86 + ( 2016 )0
17x - 4x = 82 + 1
17x - 4x = 64 + 1
17x - 4x = 65
x( 17 - 4 ) = 65
x . 13 = 65
x = 65 : 13
x = 5
Vậy x = 5
# Học tốt #
17x-4x=88:86+(2016)0
13x=82+1
13x=64+1
13x=65
x=65:13
x=5
vậy x=5

\(17x-4x=65\)
\(\left(17-4\right)x=65\)
\(13x=65\)
\(x=65:13\)
\(x=5\)
Vậy x=5
Bài làm
17x - 4x = 65

17x + 3. ( -16x – 37) = 2x + 43 - 4x
<=>17x-48x-111=-2x+43
<=>-29x=154
<=> \(x=-\frac{154}{29}\)
-3. (2x + 5) -16 < -4. (3 – 2x)
\(\Leftrightarrow-6x-31< -12+8x.\)
\(\Leftrightarrow-14x< 19\Rightarrow x< -\frac{19}{14}\)
17x - 4x = 8^8 : 8^6 + ( 2016 )^0
= 17x - 4x = 65
=> ( 17 - 4 ) . x = 65
=> 13x = 65
x = 65 : 13
x = 5
