In this section there are 6 questions. For each show all necessary work on the space provided. Each is worth 4 points. Put your final answer in Circle or Box. Solve 7x + 3 = 6(x - 1) + 9 7x + 3 = 6x - 5 + 9 7x + 3 - 3 = 6x + 3 - 3 Rent-a-Heap Agency charges $125 per week plus $0.20 per mile to rent a small car. How many miles can you travelled for $335. Given Ax + By = C, Solve for y.

Solution

1 ) Given that

7x + 3 = 6(x-1) + 9

7x + 3 = 6x - 6 + 9

7x + 3 = 6x + 3

7x - 6x = 3 - 3

x = 0

Therefore ,

The solution is , x = 0

3 ) Given that

Ax + By = C

By = C - Ax

y = (C - Ax) / B
