12x + 2 (3x - 7) - 8 please show your work
wariber [46]

Answer:

18x - 22

Step-by-step explanation:

12x +<u> 2 (3x - 7)</u> - 8

underlined section is indicating that you need to multipy

so 2 mulitiplied by 3x is 6x

and  2 multiplied by 7 is 14

your new expression should look like this:  12x + (6x -14) - 8

now to simplify the expression you combine like terms, so combine the integers, and combine the X numbers.

so 12x and 6x = 18x

and (-14) and (-8) comes out to (-22)

this is the final answer:

18x - 22
