Hello, I'll try to make this as easy to understand as possible, anyways, let's begin:
First off, we need to do the multiplication on the right side, like this:
7 + 2x = 2(x - 1) + 4
↓
7 + 2x = 2x - 2 + 4
Now, we need to pass all the x's to one side, and the numbers to the others, like so:
7 + 2x = 2x - 2 + 4
↓
-2x + 2x = - 7 - 2 + 4
Then, we do the addition and subtraction:
-2x + 2x = - 7 - 2 + 4
↓
0x = -5
This means that...
The equation has no solution.
Hope this helped! c:
