-(2n-1)+6(n+3)=-4-(7n-11)

n = -12/11

Step-by-step explanation:

4n = -7n - 12

4n + 7n = -7n - 12+7n

11n = -12

11n/11 = -12/11

Step-by-step explanation:

-2n+1+6n+3 = -4 -7n+11

4+4n = 7- 7n

4-7 = -7n- 4n

-3/-11 = -11n/-11

n= 3/11

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
