- 7x + 1 + 8x = x + 1
x + 1 = x + 1. . . .Both sided of the equation are the same. The results are zero after transposing

First you upload up like words so the the realm of the equation turns into 7x -a million. Then upload one to bothside and also you may get 7x=7x+2. Then subtract 7x from each and each and every section and also you may detect 0=2 which means there is no longer any answer. because 0 does now no longer equivalent 2

this is a linear equation, with a variable x.
move terms with x's to one side and numbers to the other side. Remember that when you change the side you also change the sign.
Your equation becomes:
-7x+8x-x=1-1 - x changed the sign as it was on the right and now is on the left.
after collecting like terms you get 0=0
which means that your equation is an identity and has infinite number of solution. The equation is true for any value of x.

-7x +1+8x = x + 1
-7x +8x -x = +1 -1
x-x = 0
answer is 0

-7x+1+8x=x+1
-7x+8x-x = 1-1
0 = 0 (does NOT mean x=0)
Are you sure you copied the equation correctly??

-7x + 1 + 8x = x + 1
Group like terms.
x + 1 = x + 1
Eliminate the variable by subtracting x both sides.
1 = 1
Notice we end up with a statement having no variables. We then determine if this is true or false. In this case, it is true, and x is equal to all real numbers.
(If our statement was false, our answer would be no solution).

Take x to the left to its sign changes from + to -
The equation becomes....
-7x - x + 8x + 1 = 1..... Clear all x...
-8x + 8x = +1 - 1
so solution set is all numbers...

ok first combine like terms
-7x+8x= x
so it's x+1=x+1 which is equal..so there is no answer

First take L.H.S.
Let x=1,
L.H.S.=-7x+1+8x (put the value x=1)
-7(1)+1+8(1)=-7+1+8=2
Now put the same value of x in the R.H.S.
R.H.S.=x+1=1+1=2
So L.H.S.=R.H.S.
Now let x=2,
L.H.S.=-7(2)+1+8(2)=-14+1+16=3
R.H.S.=2+1=3
again L.H.S.=R.H.S.
So we can say
-7x+1+8x=x+1.(Because the eq. is true for all values of x)
Thankyou.

-7x+1+8x=x+1
x+1=x+1
x+1-1=x+1-1
x=x(1=1)
