Question
Simplify $3x – 5 – x + 9$ and find the value if $x = 3.$
✓
Answer
The given expression is:
$3x - 5 - x + 9$
$= 3x - x - 5 + 9$
$= 2x - 5 + 9$
$= 2x + 4$
Put $x = 3,$ we get
$2x + 4 = 2(3) + 4$
$= 6 + 4$
$= 10$
$3x - 5 - x + 9$
$= 3x - x - 5 + 9$
$= 2x - 5 + 9$
$= 2x + 4$
Put $x = 3,$ we get
$2x + 4 = 2(3) + 4$
$= 6 + 4$
$= 10$
