2. 3/2 = 1.5. 3. 7. 5. 7/5 = 1.4. 4. 17. 12. 17/12 = 1.416666. 5. 41. 29. 41/29 = 1.413793. 1.3(c) 1.7(c).  let P2k = Xk and q2k = 2Yk.

Step-by-step explanation:

-3.8x + 7 and c = -75/14 and/or c = -5.35714

## Step-by-step explanation:

First equation:

1.2x + 7 – 5x =

Step 1 – Group like terms:

1.2 – 5x + 7

Step 2 – Add simliar elements:

1.2 x – 5x = -3.8x =

3.8x + 7

Second equation:

2.2c – 3 = 2(6 – c) + 7c =

Step 1 – Multiply both sides by 10:

2.2c ⋅ 10-3 ⋅ 10 = 2(6 – c) ⋅ 10 + 7c ⋅ 10

Step 2 – Refine:

22c – 30 = 20(6-c) + 70c =

– Expand 20(6-c): 120 – 20c

22c – 30 = 120 – 20c + 70c

Step 3 – Add similar elements:

-20c + 70c = 50c =

22c – 30 = 120 + 50c

Step 4 – Add 30 to both sides:

22c – 30 + 30 = 120 + 50c + 30

Step 5 – Simplify:

22c = 50c + 150

Step 6 – Subtract 50c from both sides:

22c – 50c = 50c + 150 – 50c

Step 7 – Simplify:

-28c = 150

Step 8 – Divide both sides by -28:

-28c/-28 = 150/-28

Step 9 – Simplify:

c = -75/14
