Answer:
<h2><em><u>x = 4</u></em></h2>
Explanation:
10 + 6x + 2x - 7 = 35
- Add Similar Elements: 6x + 2x = 8x
10 + 8x - 7 = 35
8x + 10 - 7 = 35
8x + 3 = 35
- Subtract 3 From Both Sides
8x + 3 - 3 = 35 - 3
8x = 32
8x / 8 = 32 / 8
<h2><u><em>x = 4</em></u></h2>
Here's a way to do it.
Let 4e +2 = 5n +1 . . . . . . for some integer n
Then e = (5n -1)/4 = n + (n -1)/4
We want (n-1)/4 to be an integer, so let it be integer m.
... m = (n -1)/4
... 4m = n -1
... 4m +1 = n
Substituting this into our expression for e gives
... e = (5(4m+1) -1)/4 = (20m +4)/4 = 5m +1
e = 5m+1 for any integer m
This is simple division:

So, plug it into your calculator and you get:

Your answer's that
