Distribute the 4 to the x - 3 to get 4x - 12
4x - 12 - 2x + 9; combine like terms (4x and -2x, -12 and 9)
You're left with 2x - 3
Answer: 2x-3
Step-by-step explanation:
First expand whatever u've got in brackets.
Then u get
4x - 12 - 2x + 9
then combine like terms.
(4x - 2x) + (-12 + 9)
2x + (-3)
= 2x - 3
Hope it's good:)
