Answer:
x= 8
x= -8
Step-by-step explanation:
|x+1| /3 = 3
|x+1| = 9
|x| + |1| = 9
|x| = 8
x= 8
x= -8
X-y is positive when y is further away from 0, compared to x. In other words, when y is a larger negative
For example
x = -2
y = -5
x-y = -2-(-5) = -2+5 = 3
10*30=300
10*4=40
6*30=180
6*4=24
add them up: 300+40+180+24=544
