Solve for x.

a. x/2 - x + 2/17 = 3

x=-98/17

Step-by-step explanation:

1) simplify

(1/2x + -x) + (2/17) = 3 -- combined like terms

2) subtract 2/17 from both sides

-1/2x = 49/17

3) multiply both sides by 2/-1

x = -98/17

$112

Step-by-step explanation:

Brad puts an equal amount of money in his savings account once a month. He started with $27.

The next month, he had $44 in his account. The difference between these amounts are $17.

Two months after that, he had $78 in his account. The difference between these amounts are $34.

where,

is the amount of money in the account and n is the month.

Putting , we get
