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

Dylan is 15, which is 3 years older than twice his sister Savannah’s age. How old is savannah
Brrunno [24]

Answer:

Savannah's age = 6 years

Step-by-step explanation:

Let

Savannah's age = x

Dylan's age = 15

Dylan is 15, which is 3 years older than twice his sister Savannah’s age

Dylan = 2x + 3

Find Savannah's age

2x + 3 = 15

Subtract 3 from both sides

2x + 3 - 3 = 15 - 3

2x = 12

Divide both sides by 2

2x / 2 = 12 / 2

x = 6

Therefore,

Savannah's age = x

= 6 years

Dylan's age = 2x +3

= 2*6 + 3

= 12 + 3

= 15 years
