Answer 2

To solve the equation $\frac{X-2}{2} \frac{2}{9} = -3 \frac{3}{4}$, we can follow these steps:

Step 1: Convert the mixed number $-3 \frac{3}{4}$ to an improper fraction. Step 2: Multiply both sides of the equation by $\frac{9}{2}$ to eliminate the fraction on the left side. Step 3: Solve for $X$.

Let's start with Step 1:

Step 1: Convert $-3 \frac{3}{4}$ to an improper fraction: To do this, we multiply the whole number (-3) by the denominator (4) and add the numerator (3). The result becomes the new numerator, and the denominator remains the same (4). $-3 \frac{3}{4} = -\frac{3 \times 4 + 3}{4} = -\frac{15}{4}$

Step 2: Multiply both sides by $\frac{9}{2}$: $\frac{9}{2} \times \frac{X-2}{2} \times \frac{2}{9} = -\frac{15}{4} \times \frac{9}{2}$

Now, the $\frac{2}{9}$ on the left side cancels out, as well as the $\frac{9}{2}$ on the right side:

$X - 2 = -\frac{15}{4} \times \frac{9}{2}$

Step 3: Solve for $X$:

Now, let's perform the multiplication on the right side:

$X - 2 = -\frac{15}{4} \times \frac{9}{2} = -\frac{135}{8}$

To isolate $X$, add 2 to both sides of the equation:

$X = -\frac{135}{8} + 2$

Now, let's find a common denominator and add the fractions:

$X = -\frac{135}{8} + \frac{16}{8} = \frac{-135 + 16}{8} = \frac{-119}{8}$

So, the value of $X$ is $\frac{-119}{8}$ or -14.875 (as a decimal approximation).
