You would subtract 4a from both sides to get 7a + 9 = 30. Then you should subtract 9 from both sides to get 7a = 21. Then divide both sides by 7. Final answer: a=3

X is a variable, while parenthesis suggest multiplication. Y equals the amount of her book left.
(1/5) + 3(1/5) + x = 1
(1/5) + (3/5) + y = 1
Combine like terms
(4/5) + x =1
Subtract four-fifths
x = (1/5)
