Answer:

1. 123

2. 0

3. 100

Step-by-step explanation:

3s - 11 + t + 7s + 9 → 3 × 13 - 11 + -5 + 7 × 13 + 9 = 123

2s - 6r - 5s + 19r - 8s → 2 × 13 - 6 × 11 - 5 × 13 + 19 × 11 - 8 × 13 = 0

14 ( 5 + s) - 13s + 17 → 14 ( 5 + 13) - 13 × 13 + 17 = 100

I hope this helps you :D

Determine the value of x for the following equations.
-10 (x + 9) = 10 (x-3)
3 (-9 - 4x)- 4 = 8x - 9 (x + 12)
11 (9 - 2x)= -(12x + 11)

Determine the value of x.
-8 (x - 6) + 2x = 30
