Answer:
Step-by-step explanation:
The equation shown above does not show the substitution property. Instead, it shows the Addition Property of Equation where 3 is added to both of its sides. This is shown below,
4x - 3 = 7
4x - 3 + 3 = 7 + 3
4x = 10
6x6x6x6x6x6x6
6^2 is 6x6
6^3 is 6x6x6
etc...
6^7 is 6x6x6x6x6x6x6
x = 7
5x-4 = 31
5x = 31+4
5x = 35
4+7/16
Answer is 11/16
