Question

solve the following equation plz fast send me answer i. will made a brainlist​

Answer 1

Answer:

n = - 3

Step-by-step explanation:

18 - 5(3 - 2n) = n - 4(n + 9)

=> 18 - 15 + 10n = n - 4n - 36

=> 10n + 3n = - 36 - 3

=> 13n = -39

=> n = -39/13 = - 3

Answer 2

Answer:

n = -3

Step-by-step explanation:

18 - 5 (3-2n) = n - 4 (n+9)

Use the distributive property to multiply -5 by 3 - 2n.

18 - 15 + 10n = n - 4 (n + 9)

Subtract 15 from 18 to get 3

3 + 10n = n-4(n+9)

Use the distributive property to multiply -4 by n+ 9

3 + 10n = n - 4n - 36

Combine n and -4n to get -3n.

3 + 10n = -3n - 36

Add or subtract the like terms where applicable.

10n + 3n = -36 -3

13n = -39

Divide -39 by 13

n = -39/13

  = -3
