x>10 or x< -2
Step-by-step explanation:
There are two solutions, one positive and one negative, remembering to flip the inequality for the negative
x-4 >6 or x-4 < -6

x-4+4 > 6+4 or x-4+4 < -6+4
x>10 or x< -2
finding the product of 2 numbers means that you have to multiply those numbers

when multiplying fractions , numerators are multiplied by numerators and denominators by denominators

therefore product of 3/8 and 16 is 6
next we have to find 2/3 of 6
'of' operator means multiplication

answer is 4
