Question
Simplify:
-x + [5y - {x - (5y - 2x)}]
-x + [5y - {x - (5y - 2x)}]
✓
Answer
We have:
Removing the innermost grouping symbol ( ) first, then { } and then [ ], we have:
-x + [5y - {x - (5y - 2x)}]
= -x + [5y - {x - 5y + 2x}]
= -x + [5y - {3x - 5y}]
= -x + [5y - 3x + 5y]
= -x + [10y - 3x]
= -x + 10y - 3x
= -x - 3x + 10y
= -4x + 10y
Removing the innermost grouping symbol ( ) first, then { } and then [ ], we have:
-x + [5y - {x - (5y - 2x)}]
= -x + [5y - {x - 5y + 2x}]
= -x + [5y - {3x - 5y}]
= -x + [5y - 3x + 5y]
= -x + [10y - 3x]
= -x + 10y - 3x
= -x - 3x + 10y
= -4x + 10y
