Question
### Algebraic Equations

Below are two algebraic equations provided for solving:

#### Equation (i):
\[ 2x + 4.5(25 - x) = 25 \]

This linear equation involves one unknown variable, \( x \). The term \( 4.5(25 - x) \) indicates a multiplication operation within the parentheses, where 4.5 is multiplied by the difference between 25 and \( x \).

#### Equation (ii):
\[ -\frac{6}{5}y - 4 = -22 \]

This is another linear equation with one unknown variable, \( y \). The equation includes a fraction, \(-\frac{6}{5}\), which is multiplied by \( y \), and a constant term, -4. The equation is set equal to -22.

### Instructions for Solving
- For Equation (i), distribute the 4.5 across the term inside the parentheses and then solve for \( x \).
- For Equation (ii), isolate the variable \( y \) by first adding 4 to both sides of the equation and then solving for \( y \) by dividing both sides by \(-\frac{6}{5}\).

These equations practice skills in algebraic manipulation, specifically in solving linear equations involving distribution and fractions.
