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.
