x

Explanation:

You solve the inequality just like you would solve an equality.

Everything that has the x on the left side, everything without x on the right side.

Be careful that when you multiply by -1, the inequality signal changes(for example, lesser than becomes higher than

So

Multiplying by -1

So the correct answer is:

x∈R, x > -2

Answer:

x∈R, x > -2

Explanation:

You solve the inequality just like you would solve an equality.

Everything that has the x on the left side, everything without x on the right side.

Be careful that when you multiply by -1, the inequality signal changes(for example, lesser than becomes higher than

So


10 < x + 12


-x < 12 - 10


-x < 2

Multiplying by -1


x > -2

So the correct answer is:

x∈R, x > -2
