không ai làm nhỉ

\(-2x-\left(x-17\right)=34-\left(-x+25\right)\)

\(-2x-x+17=34+x-25\)

\(-2x-x-x=34-25-17\)

\(-4x=-8\Leftrightarrow x=2\)

\(17x-\left(16x-37\right)=2x+43\)

\(17x-16x+37=2x+43\)

\(17x-16x-2x=-37+43\)

\(-x=6\Leftrightarrow x=6\)

\(-2x-3\left(x+17\right)=34-2\left(-x+25\right)\)

\(-2x-3x-51=34+2x-50\)

\(-2x-3x-2x=34-50+51\)

\(-7x=35\Leftrightarrow x=-5\)

14 x + 36 - 37 x = 48 - 16 x

( 14x - 37x) +16x = 48 - 36

- 23 x + 16 x = 12

-7 x =12

x = \(\dfrac{-12}{7}\)

\(14x+36-37x=48-16x\)

\(\Rightarrow14x-37x+16x=48-36=12\)

\(\Rightarrow-7x=12\Rightarrow x=-\dfrac{12}{7}\)

Chúc bạn học tốt!!!

a) -2x - (x-17) = 34-(-x + 25)

-2x- x+17= 34+x-25

-2x-x-x= -17 +34-25

-4x = -8

x = 2

b)17x-(-16x-27) = 2x+43

17x + 16x + 27 = 2x + 43

17x + 16x -2x= -27 +43

31x= 26

x= 21/31

c)- 2x- 3(x-17) = 34- 2(-x + 25)

-2x - 3x + 51 = 34 + 2x -50

-2x - 3x -2x = -51 + 34 -50

-7x = -67

x = 67/7

d) 17x +3(-16x-37) = 2x+ 43 -4x

17x -48x -111 = 2x + 43 -4x

17x - 48x -2x + 4x = 111 -43

-29x = 68

x = -68/29

14x - 6x = 2³ x 5²

        8x = 8 x 25

        8x = 200

          x = 200 : 8

          x = 25

14x - 6x = 2³ . 5²

8x = 200

=> x = 200 ÷ 8

=> x = 25

Vậy x = 25

a. 14x-5x=63

x.(14-5)=63 => 9x=63=> x=7

b. 2^x+2^x+1+2^x+2=112

2^x.(1+2+2²)=112

2^x. 7=112 => 2^x=16=2⁴ => x=4

a)14x-5x=9x=63

=>x=63:9=7

Vậy x=7

b) 2^x+2^x+1+2^x+2=2^x(1+2+2²)=112

2^x.7=112

2^x=112:7=16=2⁴

=> x=4

Vậy x=4

\(14x-6x=2^3.5^2\)

\(8x=200\)

\(\Rightarrow x=25\)

        Vậy x=25

14x - 6x = 2³.5²

14x - 6x = 200

( 14 - 6 )x = 200

8x = 200

=> x = 200 ÷ 8

=> x = 25

Vậy x = 25

14x - 2 . 7² = 42

14x=140

x=10

ghi rõ cách làm cho mình nha!!!

7^2.x-14x=7^2.10-70

49x-14x=49.10-70

(49-14)x=490-70

35x=420

x=420/35

x=12
