1 + 4x = -5 + 7x

1st step: you need to move 4x to the right and -5 to the left so that all the x's are in one place. 4x will be negative and -5 will be positive when you move them. So it will be:

1+5=7x-4x

2nd step:

3x=6

3rd step: you need to divide both sides into 3, because it is the common divisor.

x=2

To sum up:

1 + 4x = -5+7x

7x - 4x = 1 + 5

3x = 6

x = 2

You can try to memorize the summary. However, it is better to understand the solution as a whole.
