Answer:

If the question is (2/3x) = -10,

x = -(1/15) = - 0.06667

The check is presented under the explanation below

If the correct question is (2/3)x = -10,

x = -15

The check is presented under the explanation below

Explanation:

If the question is rightly written as it is in the attached document,

(2/3x) = -10

We can cross multiply and obtain

2 = -10 × 3x

-30x = 2

x = -(2/30) = -(1/15) = - 0.06667

To check

(2/3x) = -10,

(2 ÷ 3x) = -10

2 ÷ 3(-1/15) = 2 ÷ (-1/5) = 2 ÷ (-0.2) = -10 (Correct!)

If the correct question is

(2/3)x = -10

Divide both sides by (2/3)

x = -10 ÷ (2/3)

x = -10 × (3/2)

x = -15

To check

(2/3)x = -10

If x = -15

(2/3) × (-15) = -10 (Correct!)

Hope this Helps!!!

Answer:

Austerity is a set of political-economic policies that aim to reduce government budget deficits through spending cuts, tax increases, or a combination of both. Austerity measures are often used by governments that find it difficult to borrow or meet their existing obligations to pay back loans. The measures are meant to reduce the budget deficit by bringing government revenues closer to expenditures. This reduces the amount of borrowing required and may also demonstrate a government's fiscal discipline to creditors and credit rating agencies and make borrowing easier or cheaper as a result.
