Answer:
x=8.625
Step-by-step explanation:
ok so the lines mean absolute value so its actuall positive soyou get 3+8x+8=80
so add 3 and 8 to get 11+8x=80
subtract 11 to get 8x=69
then divide it by 8 so x is by itself
x=8.625 hope this helped :)
x = 3 , x = -3
3 | -8x | + 8 = 80
3 | -8x | = 72
Solve the negative and positive case:
Negative-
-3 ( -8x ) = 72
24x = 72
x = 3
Positive-
3 (-8x ) = 72
-24 = 72
-x = 3
x = -3
