If the solution of equation 2x + 1 = 3 about X is the same as that of equation 2-3 K-X = 0, find the value of K

If the solution of equation 2x + 1 = 3 about X is the same as that of equation 2-3 K-X = 0, find the value of K

By solving the equation 2x + 1 = 3, x = 1
Substituting 2-thirds of K-X = 0 leads to (k-1) / 3 = 2
The solution is k = 7

How to solve the equation that 3x + 5 equals 2x / 3 minus 1

（3x+5）/2=（2x-1）/3
9x+15=4x-2
x=17/5

If the solution of the equation 1-2x + 3 x + 1 = 1-4 2x + 1 is the same as that of the equation x + 6x-a = 6x-3x about X, find the value of a 2-3a

1-2x of 6 + X + 1 of 3 = 2x + 1 of 1-4
Double 12 on both sides
2-4x+4x+4=12-6x-3
6x=3
x=1/2
Substituting x + 6x-a = 6x-3x
1/2+(3-a)/3=(a-3/2)/6
1/2+1-a/3=a/6-1/4
a/2=7/4
a=7/2
So a-3a
=49/4-21/2
=7/4

If the solution of the equation 1-2x + 3 x + 1 = 1-4 2x + 1 is the same as that of the equation x + 6x-a = 6x-3x on X, find the value of A Let's know that the reciprocal of 3 parts of a and 2a-9 of 3 are opposite numbers to each other. Find the value of the cube of (- A + 2) 2013

1-2x + 3 x + 1 = 1-4 2x + 1
Double 12 on both sides
2(1-2x)+4(x+1)=12-3(2x+1)
2-4x+4x+4=12-6x-3
6=9-6x
6x=3
x=1/2
x+(6x-a)/3=(a-3x)/6
Multiply both sides by 6
6x+12x-2a=a-3x
21x=3a
therefore
a=7x=7/2

If the solution of the equation x + 1-1 = 1-quarter 2x + 1 is the same as x + 6 / 3, x-a = 6 / 6 a-3x, the value of a is calculated

To solve the equation (x + 1) / 6-1 = 1 - (2x + 1) / 4
2x+2-24=-6x-3
8x=19
x=19/8
Finishing x + (6x-a) / 3 = (a-3x) / 6
6X + 12x-2a = a-3x
21x=3a
That is, a = 7x = 57 / 8

If the solution of equation 1-2x / 6 + X + 1 / 3 = 3-2x / 4 is the same as the solution of equation x + 6x-a / 3 = a-18x / 6 for X, find the value of A

1-2x/6+x+1/3=3-2x/4
2(1-2x)+4(x+1)=3(3-2x)
6=9-6x
6x=3
x=1/2
X + 6x-a / 3 = a-18x / 6
1/2+(3-a)/3=(a-9)/6
3+2(3-a)=a-9
3a=18
A=6

If the solution of equation 1-2x / 6 + (x + 1) / 3 = 1 - (2x + 1) / 4 is the same as that of equation x + (6x-a) / 3 = A / 6-3x about X, try to find the value of a (A-1)

By solving the equation 1-2x / 6 + (x + 1) / 3 = 1 - (2x + 1) / 4, x = - 7 / 6
Substituting into the equation x + (6x-a) / 3 = A / 6-3x
A is obtained
Then a (A-1) is obtained

It is known that 2x + 7m = - 3 has the same solution as the equation 2-3 (3m-x = 0)

2-3 parts 3m-x = 0
That is, 2 = 3 / 3m-x
3m-x=6
x=3m-6
2X + 7m = - 3, that is 2x = - 3-7M
So - 3-7M = 2 (3m-6)
That is - 3-7M = 6m-12
That is, 13m = 9
m=9/13
