x = 2, so substitute it in into each equation
the first equation : 7^2 + 4(x) is now 7^2 + 4(2). PEMDAS would give you 49 + 4(2), and then 49 + 8 to get 57.
the second equation : 4x + (7*7). PEMDAS to get 4(2) + 49, then 8 + 49, so it is also 57.
they are the same. another way to tell is w the commutative property, which stated that the order in which the values are ordered does not affect the answer, and because 7^2 is the same thing as 7*7.
