Question
Simplify $6x + 5(x – 2)$ and find the value if $x$ is equal to $2.$
✓
Answer
The given expression is: $6x + 5(x - 2)$
Opening the brackets, we get
$6x + 5x - 10 = 11x - 10$
Put $x = 2,$ we get
$11x - 10 = 11(2) - 10$
$= 22 - 10 = 12$
Opening the brackets, we get
$6x + 5x - 10 = 11x - 10$
Put $x = 2,$ we get
$11x - 10 = 11(2) - 10$
$= 22 - 10 = 12$
