Solve the equation. Check your answer.

29 equals 8 x plus 5 minus 4 x

1 answer

To solve the equation \( 29 = 8x + 5 - 4x \), let's first simplify the right side.

  1. Combine like terms \( 8x \) and \( -4x \):

\[ 29 = (8x - 4x) + 5 \]

\[ 29 = 4x + 5 \]

  1. Next, isolate \( 4x \) by subtracting 5 from both sides:

\[ 29 - 5 = 4x \]

\[ 24 = 4x \]

  1. Now, divide by 4 to solve for \( x \):

\[ x = \frac{24}{4} = 6 \]

Now, let's check the solution by substituting \( x = 6 \) back into the original equation:

  1. Substitute \( x = 6 \) into \( 8x + 5 - 4x \):

\[ 8(6) + 5 - 4(6) \]

\[ = 48 + 5 - 24 \]

\[ = 29 \]

Since both sides of the equation match, the solution \( x = 6 \) is correct.

Thus, the answer is:

\[ \boxed{6} \]
