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