What would happen if currency in all countries had fewer denominations, i. E. Fewer varieties of coins or numbers of bills? People would be more likely to confuse the value of currencies. Exchanging money between countries would be much easier. People could not charge as many different prices for goods. All goods would be more expensive than they currently are.

People could not charge as many different prices for goods.

Explanation:

edge 22

simplify brackets

8 - 2a - 7 = a + 40

simplify 8 - 2a - 7 to -2a + 1

-2a + 1 = a + 40

add 2a to both sides

1 = a + 40 + 2a

simplify a + 40 + 2a to 3a + 40

1 = 3a + 40

subtract 40 from both sides

1 - 40 = 3a

simplify 1 - 40 o -39

-39 = 3a

divide both sides by 3

-39/3 = a

simplify 39/3 to 13

-13 = a

switch sides

a = -13
