Answer:
18x - 22
Explanation:
12x + 2 (3x - 7) - 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
