What is the twice the difference of a number and four is less then eight

n < 8

{n|n are all rational numbers less than positive 8}

Step-by-step explanation:

If you convert it, it'll be:

2 × ( n - 4 ) < 8

Distribute 2:

2n - 8 < 8

2n - 8 + 8 < 8 + 8

2n < 16

2n/2 < 16/2

n < 8

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
