Question
Simplify the following algebraic expressions by removing grouping symbols: $2x + (5x - 3y)$
✓
Answer
We have, $2x + (5x - 3y)$ Since the $'+'$ sign precedes the parentheses,
we have to retain the sign of each term in the parentheses when we remove them.
$= 2x + 5x - 3y = 7x - 3y$
we have to retain the sign of each term in the parentheses when we remove them.
$= 2x + 5x - 3y = 7x - 3y$
