Simplify.
6(3x - 5) + 2(3x - 5) - 8(3x - 5)

Answers

Answer 1
Answer:

Answer:

0 is the correct answer

Step-by-step explanation:

Distribute the 6, 2, and -8 to get 18x - 30 + 6x - 10 - 24x + 40, which combines to 0.
Answer 2
Answer: The way to simplify this is so combine like terms. Do the equation in the bracket but leave the variable (3x - 5) = (- 2x) So now the equation looks like this: 6(-2x) + 2(- 2x) + 8(- 2x) And now you do the multiplication, but still leave the variable 6(- 2x) = (- 12x) Now the equation is: (- 12x) + (- 4x) - (- 16x)

2 ( x - 5 ) - 6 x = - 22

2 * x - 2 * 5 - 6 x  = -22

2 x - 10 - 6 x = -22

2 x - 6 x = - 22 + 10
