If daniels age is x years we can create the equation:_

3x = x + 4
2x = 4
x = 2 

so Daniel is 2 years old

Answer:

Takeru bought 72 eggs and baked  18 soufflés .

Step-by-step explanation:

Let

e = number of eggs Takeru bought.

s = number of soufflés Takeru bought.

Then we know that Takeru  bought 4 times as many eggs as he baked soufflés, therefore:

e=4s.

And since for every soufflés Takeru bakes he uses 3 eggs, and after backing he has 18 eggs left, we have:

e-3s=18 <em>This says that from e eggs there are 18 eggs left after Tkeru used three eggs for each soufflé.</em>

Now we have two equations:

(1).e=4s.

(2).e-3s=18

We put the value of e from equation (1) into equation (2) and solve for s and get:

s=18

e=4s=4*18=72.

Thus

Number of eggs Takeru bought = 72.

Number of soufflés Takeru bought = 18.

Answer:

a = 6

Step-by-step explanation:

Hello!

Solve:

  • 4(3a - 4) = 56
  • 3a - 4 = 14          (factoring out 4)
  • 3a = 18               (adding 4 to both sides)
  • a = 6                   (dividing by 3)

Another way:

  • 4(3a - 4) = 56
  • 12a - 16 = 56        (distributive property)
  • 12a = 72               (moving like terms)
  • a = 6                    (dividing by 12)

Distributive Property of Multiplication:

The process of distributing the outside factor to the terms in the parenthesis.

Example:

4(3a - 4)\\\\4(3a) - 4(4)\\\\12a - 16
