Answer 2

To solve the equation $\frac{x}{3} + \frac{x}{4} = -21$, we'll first find a common denominator to combine the fractions:

$\frac{4x}{12} + \frac{3x}{12} = -21$.

Now, we can combine the fractions:

$\frac{4x + 3x}{12} = -21$.

Combine the numerators:

$\frac{7x}{12} = -21$.

Now, we'll isolate $x$ by multiplying both sides by 12 to get rid of the fraction:

$7x = -21 \times 12$.

$7x = -252$.

Now, divide both sides by 7 to find $x$:

$x = \frac{-252}{7}$.

$x = -36$.
