(1 point) For this problem, you want to prove the following:\

AAxinZ,EEkinZ such that k+4.7x

\ Which of the following is the best starting point for a direct proof?\ Let

x

be an integer number and

k

an integer.\ Let

k

be an integer for a given integer number

x

.\ Suppose

k+4.7x

\ Let

x

be any integer.\ Let

k

be an integer\ None of these\ Which of the following is the best second step to follow the initial statement above?\ Since 4.7 and 75 are positive then

75-47x

is positive\ Let

k

be an integer for a given integer number

x

.\ Then there exists an integer

k

such that

k+47x

.\ Since

x

is fixed,

75-47x

is finite.\ Let

k

be an integer\ Using the first two sentences from above, complete a proof of this statement
