Question

−4[3x − (x + 2)]

Answer 1

Do you want me to explain it, or just lay the numbers out?

Answer 2

both please

Answer 3

Our goal here is to to simplify this. According to PEMDAS, we should start with wehat's in the parentheses. But because x +2 cannot be simplified, then we can move on to what's outside the parentheses. And that's the subtraction sign.
We distribute the negative sign, so it becomes
−4[3x −x - 2)]

Answer 4

Now we can combine the like terms
−4[2x - 2]
We can't simplify what's inside the brackets anymore, so now we can just distribute the -4
-8x + 8
And that's your answer!

Answer 5

You can check your answer too by substituting x with a random number like 0 or 1.
−4[3x − (x + 2)]
−4[3*(0) − ((0) + 2)]
−4[3*0 − (2)]
−4[0 − 2]
−4[− 2]
8
-8x + 8
-8(0) + 8
0 + 8
8

Answer 6

Woops actually -8(x-1) is the last step to simplify it. What we did was factor -8 from -8x + 8.
