Answer 1

SOLUTION

TO DETERMINE

Expand to write an equivalent expression

$\displaystyle \sf{ - \frac{1}{2} ( - 2x + 4y )}$

EVALUATION

Here the given expression is

$\displaystyle \sf{ - \frac{1}{2} ( - 2x + 4y )}$

Hence the required equivalent expression is

$\displaystyle \sf{ - \frac{1}{2} ( - 2x + 4y )}$

$\displaystyle \sf{ = - \frac{1}{2} \times (- 2x) + ( - \frac{1}{2} ) \times 4y }$

$\displaystyle \sf{ =x - 2y}$
