5 1/2 x+2/3 x=37

1. x = 37
2. x = 6
3. 37x = 6
4. 37/6 x=37
5. 11/2 x+2/3 x=37

1 answer

To solve the equation \(5 \frac{1}{2} x + \frac{2}{3} x = 37\), we will first convert \(5 \frac{1}{2}\) to an improper fraction.

\[ 5 \frac{1}{2} = \frac{11}{2} \]

Now we can rewrite the equation:

\[ \frac{11}{2} x + \frac{2}{3} x = 37 \]

Next, we need to find a common denominator to combine the fractions on the left side. The least common multiple of 2 and 3 is 6. We will convert each term:

\[ \frac{11}{2} x = \frac{11 \cdot 3}{2 \cdot 3} x = \frac{33}{6} x \] \[ \frac{2}{3} x = \frac{2 \cdot 2}{3 \cdot 2} x = \frac{4}{6} x \]

Now we can combine these:

\[ \frac{33}{6} x + \frac{4}{6} x = 37 \] \[ \frac{37}{6} x = 37 \]

To solve for \(x\), we multiply both sides by the reciprocal of \(\frac{37}{6}\):

\[ x = 37 \cdot \frac{6}{37} \]

The \(37\) cancels out:

\[ x = 6 \]

Thus, the solution is:

\[ \boxed{6} \]

Looking at the options given:

  1. \( x = 37 \)
  2. \( x = 6 \) (Correct!)
  3. \( 37x = 6 \)
  4. \( \frac{37}{6} x = 37 \)
  5. \( \frac{11}{2} x + \frac{2}{3} x = 37 \) (This is the original equation!)

The correct answer from the choices is option 2.
