If - 3 (x+2) = 15 what is the value of 2x-1

-3 (x+2) = 15

use the distributive property and multiply

you then get

-3x - 6 = 15

add 6 to both sides to cancel out the - 6

you get - 3x = 21

divide 21 by - 3

you get x = 7

but that's only the first part, since you now have x, plug in the value (7) for x

2 (7) - 1

multiply 2 times 7 and you get

14 - 1

your final answer:

13
