Answer:
x - 17.95 = 71.80, $89.75
Step-by-step explanation:
Let the original price of the headphones be x
Amount of coupon = $17.95
You pay the final amount for the headphones after using the coupon = $71.80
So to find the original price of the headphones, the equation will be
x - 17.95 = 71.80
x = 17.95 + 71.80
x = $89.75
The original price of the headphones would be $89.75
X>7→because if x=7 the answer is 8 so it should be >7
x<-1→if 2|-1-3|=8. →-2 &-3&-4&...are smaller than -1→x<-1
