Understand the Problem
The question is asking to solve a mathematical equation for the variable m. This will require simplifying the left side of the equation and isolating m on one side.
Answer
\( m = \frac{3}{2} \)
Answer for screen readers
The final answer is ( m = \frac{3}{2} ).
Steps to Solve
- Combine like terms on the left side
First, we need to combine all terms involving $m$ on the left side of the equation:
$$ \frac{2}{3}m + \frac{1}{6}m - \frac{1}{2}m - 2 + \frac{3}{2} = 0 $$
- Convert to a common denominator
To combine the fractions with $m$, we need a common denominator. The least common multiple of 3, 6, and 2 is 6. Rewrite the fractions:
- $ \frac{2}{3}m = \frac{4}{6}m $
- $ \frac{1}{6}m = \frac{1}{6}m $
- $ -\frac{1}{2}m = -\frac{3}{6}m $
Now we can combine them:
$$ \left( \frac{4}{6}m + \frac{1}{6}m - \frac{3}{6}m \right) $$
- Simplify the left side
Combine the coefficients of $m$:
$$ \frac{4 + 1 - 3}{6}m = \frac{2}{6}m $$
This simplifies to:
$$ \frac{1}{3}m $$
The equation now looks like:
$$ \frac{1}{3}m - 2 + \frac{3}{2} = 0 $$
- Combine constant terms
Now combine the constants on the left:
$$ -2 + \frac{3}{2} = -\frac{4}{2} + \frac{3}{2} = -\frac{1}{2} $$
So the equation is:
$$ \frac{1}{3}m - \frac{1}{2} = 0 $$
- Isolate m
Add $\frac{1}{2}$ to both sides:
$$ \frac{1}{3}m = \frac{1}{2} $$
Next, multiply both sides by the reciprocal of $\frac{1}{3}$, which is 3:
$$ m = 3 \times \frac{1}{2} $$
- Calculate the result
Thus:
$$ m = \frac{3}{2} $$
The final answer is ( m = \frac{3}{2} ).
