4.2x - 1.4y = 2.1 - 2x

Subtract 4.2x

-1.4y = 2.1 - 6.2x

Divide by -1.4

y = -3/2 + 9/2x

Answer: y = 9/2x - 3/2

For six you can write 1/4 because there is 4 pennies and 1 represents each penny


for number 5 you can put 2/10 because there is 10 coins and 2 quarters

and for number 7 is that Bradley has 10 coins not 9 so it would be 1/10
