Answer: 6(x+7)-2 = 6x+40
Step-by-step explanation:
1. First, distribute the 6 to (x+7).
6 times X = 6x and 6 times 7 = 42
2. Now we are left with the following equation: 6x+42-2
3. Combine like terms: 42-2=40
4. The final answer is 6x+40

Answer:
c = 13d
Step-by-step explanation:
Given:
4d=1/3(c-d)
Open bracket
4d = 1/3c - 1/3d
Add 1/3d to both sides
4d + 1/3d = 1/3c
Simply 4d + 1/3d
12d+d/3 = 1/3c
13/3d = 1/3c
Make c the subject of the formula
c = 13/3d ÷ 1/3
c = 13/3d × 3/1
c = 13d
