the answer is: x=5
7x5 = 35
6x5=30
35-30=5
so, 7x-5=6x

Its simple
7x - 5x=6x is a two step equation
just subtract then divide
7x-5=6x First
-5= 6x-7x since 7x and 6x are like terms you can combine them
by subtracting 7x on both sides to get teh x's on one
side and the constant on the other
-5= -x simplify
x=5 since -x = -5 then positive x must equal positive 5.
that is because you must multiply both sides by
-1

First you need to get all of the x's on one side of the equation, so to do that we need to subtract 7x from both sides.
7x - 7x - 5 = 6x - 7x
-5 = 6x - 7x
We can 6x and 7x which gives us:
-5 = -1x or
-5 = -x
Now we need to turn the -x positive, which we can do by dividing by -1
-5 / -1 = -1x / -1
which gives us the solution of:
5 = x

7x – 5 = 6x
7x - 6x = 5
x = 5

7x-5=6x
7x-6x=5 take 6x to the left side making the + sign to -and 5 to the right hand side making the - sign +.
x=5

First you isolate the variable, by subtracting 6x from each side of the equation.
That gives you x-5=0. Then add 5 to each side that gives you x=5

7x – 5 = 6x
7x-6x=5
1x=5
x=5/1
x=5
