<h3><u>The value of x is equal to 2.</u></h3>

4(x + 1) = 12(3 - x)

<em><u>Distributive property on both sides.</u></em>

4x + 4 = 36 - 12x

<em><u>Add 12x to both sides.</u></em>

16x + 4 = 36

<em><u>Subtract both sides by 4.</u></em>

16x = 32

<em><u>Divide both sides by 16.</u></em>

x = 2

Jeff has five less than twice the number of clients that Kenan has. The product of the number of clients they have is 322. Write
HACTEHA [7]

Answer:

The equation that represents this situation is 2c² - 5c - 322 = 0

Step-by-step explanation:

∵ Kenan has c clients

∵ Jeff has five less than twice the number of clients that

   Kenan has

- That means multiply c by 2 and then subtract 5 from the

   product to find the number of Jeff's clients

∴ Jeff's clients = 2c - 5

∵ The product of the number of clients they have is 322

∴ c × (2c - 5) = 322

- Multiply c by the bracket (2c - 5)

∴ (c)(2c) + (c)(-5) = 322

∴ 2c² + (-5c) = 322

- Remember (+)(-) = (-)

∴ 2c² - 5c = 322

- Subtract 322 from both sides

∴ 2c² - 5c - 322 = 0

The equation that represents this situation is 2c² - 5c - 322 = 0
