It may be a little more difficult than that.,It's more to count.,But if it's a junior high school homework.,The teacher should be more satisfied.,After all, it's too easy for the teacher to scold ==.

8-x=5 2x+5=9 x+5=8 4x=8 x+4=2x

5x=25 x+5=5 x-8=2 6x=36 6x=9

5x+4=24 6x-1=36 3x+5=14 5x=6x-5 8x-5=3

5x-3x=4 6x-5x=9 2x+3x=25 x+6=10 2x=18

I don't know your extent, but I randomly came up with a few of them, hoping it will help you (* hee-hee......

Go to the library and sift through it.

Should help.

（1）3（x-2）=2-5(x-2)

3x-6=2-5x+10

8x=18x=9/4

2 ) 2 (x+3)5(1-x)=3(x-1) Write the question clearly!

3）3(x+1)-2(x+2)=2x+33x+3-2x-4=2x+3

x=4x=-4

4) 3(x-2)+1=x-(2x-1)3x-6+1=-x+1

4x=6x=3/2

Hope it helps! Satisfied

1/2bx+2/3=x+b/3

1/2bx-x=b/3-2/3

1/2b-1)x=(b-2)/3

b-2)/2 *x =(b-2)/3

x=2/34x+b=ax-8(a≠4)

ax-4x=b+8

a-4)x=b+8

x=(b+8)/(a-4)

n(nx-1)=x+1

n^2x-n=x+1

n^2x-x=n+1

n^2-1)x=n+1

n+1)(n-1)x=n+1

When n=-1, the two sides of the equation become 0=0, then the equation has an infinite number of solutions, and when n≠-1, the two sides of the equation can be reduced to (n+1), at which point (n-1)x=1 In this case, when n=1, the equation becomes 0=1, and the equation has no solution.

When n≠1 x=1 (n-1).

x/3+a x/2-1/6(x-12)=0x/3+a x/2-1/6x+2=0

1/3+a/2-1/6)x+2=0

1/3+a/2-1/6)x=-2

When 1 3+a 2-1 6=0 there is no solution to the equation at this time a= - 1 3 when (1 3+a 2-1 6)x= - 2 the equation has an infinite number of solutions x is uncertain, so no matter what value a takes, the equation has no infinite solutions.

5x+2m=3x-7, deformed: 2m=3x-7-5x=-2x-7 Substituting 2m=-2x-7 into the second equation 3x+2m=6x+1 gives 3x+2x-7=6x+1, deformed as: 3x+2x-6x=1+7, that is, -x=8, that is, x=-8

Substituting x=-8 into 2m=-2x-7 gives 2m=-2*(-8)-7=16-7=9, and gets m=9 2=m=

From 5x+2m=3x-7 x=-2m-7 2 from 3x+2m=6x+1 to obtain x=2m-1 3 by simultaneous x=-2m-7 2 and x=2m-1 3 to obtain m=
