-6(-5n+3)+2=-166<br><br> PLEASE HELP ;(((((((

Stells [14]

Answer:

n = -5

Step-by-step explanation:

-6(-5n+3)+2=-166

distribute the -6

- 6 * -5n = 30n

-6 * 3 = - 18

30n - 18 + 2 = -166

combine like terms

30n - 16 = -166

add 16 to both sides

30n = -150

divide both sides by 30

30n/30=n

-150/30=-5

we're left with n = -5
