Answer:
(-3;6]
Step-by-step explanation:
-9<4x+3≤27 |-3 (because we have to remove everything what's next to the x)
-9-3<4x+3-3≤27-3
-12<4x≤24 |:4
-12:4<4x:4≤24:4
-3<x≤6
x = (-3;6]
Hope this helps!
(x = -20) if what your saying is 6 = -2x - 4 and (x = -16) if what your saying is x = -2 x 6 - 4
Anything to the zeroth power is 1, so the answer is just 1.
