What is the value of x in the equation: 4(2x + 1) = 27 + 3 (2x - 5)

1 answer

To solve the equation \( 4(2x + 1) = 27 + 3(2x - 5) \), let's first expand both sides.

Start with the left side:

\[ 4(2x + 1) = 8x + 4 \]

Now expand the right side:

\[ 3(2x - 5) = 6x - 15 \]

Then, we rewrite the right side:

\[ 27 + 3(2x - 5) = 27 + 6x - 15 = 6x + 12 \]

Now we have the equation:

\[ 8x + 4 = 6x + 12 \]

Next, we can isolate \( x \) by subtracting \( 6x \) from both sides:

\[ 8x - 6x + 4 = 12 \]

This simplifies to:

\[ 2x + 4 = 12 \]

Next, subtract 4 from both sides:

\[ 2x = 12 - 4 \] \[ 2x = 8 \]

Now, divide both sides by 2:

\[ x = \frac{8}{2} = 4 \]

Thus, the value of \( x \) is:

\[ \boxed{4} \]
