The given condition is:
If 5x + 7 = 2x =1, then 3x + 7 = -1
=> This given equation represent  a subtraction property of equality.
=> 5x +7 =2x-1
=> 5x – 2x + 7 = -1
=> 3x + 7 = -1

What we did was  we subtracted 2x from 5x to get the 3x
Subtraction property of equality is a mathematical process in where we subtract numbers from both sides that contains the same expression.
Like 5x and 2x, since they have the same equation, we both subtracted both numbers and the rest remains as it is.
