x ∈ (-2,−∞)*******
x ∈ (-2, ∞)
x ∈ (−∞,3)

x ∈ (-2,−∞)

Step-by-step explanation:

x ∈ (-2,−∞)

this is the answer to the question

OK decimals and fraction,s can be annoying but here is a way to do them.

Step-by-step explanation:

When you have a decimal you might find it easier to turn it into a fraction

With a fraction such as =1 You can multiply it by the denominator which is the bottom part of the fraction. So multiplying the previous equation by y you get 2x=y

with parentheses such as 4(3x+4y)=1 you are really just multiplying both the inside components by for so 4(3x+4y)=1 is equal to 12x+16y=1

I hope this helps for more help friend me, or respond in the comments
