Which algebraic expression is equivalent to this expression?

6 (3x-1) + 9x

27x-6

Step-by-step explanation:

To distribute 6 (3x-1) properly, 6 needs to be multiplied with 3x and - 1.

6 * (-1) = -6,

3x*6=18x.

Without simplifying, the answer we get from this is 18x+9x-6. 18x+9x=27x, so the algebraic expression equivalent to 6 (3x-1) + 9x is 27x-6.
