Solve the following equation for x: 6(4x + 5) = 3(x + 8) + 3. Round to the nearest hundredth.
Vera_Pavlovna [14]

Answer:

\boxed {x = -\frac{1}{7}}

Step-by-step explanation:

Solve for the value of x:

6(4x + 5) = 3(x + 8) + 3

-Use <u>Distributive Property</u>:

6(4x + 5) = 3(x + 8) + 3

24x + 30 = 3x + 24 + 3

-Combine like terms:

24x + 30 = 3x + 24 + 3

24x + 30 = 3x + 27

-Take 3x and subtract it from 24x:

24x + 30 -3x = 3x - 3x + 27

21x + 30 = 27

-Subtract both sides by 30:

21x + 30 - 30 = 27 - 30

21x = -3

-Divide both sides by 21:

\frac{21x}{21} = \frac{-3}{21}

x = \frac{-3}{21}

-Reduce the fraction to the lowest term by extracting and canceling out 3:

x = \frac{-3\div3}{21 \div 3}

\boxed {x = -\frac{1}{7}}

Therefore, the value of x is -\frac{1}{7}.
