Question

Solve these equations.
a) 54 = 9d b) n + 2 = - 14 – n

Answer 1

a) To solve for d in the equation 54 = 9d, we can divide both sides by 9:
54/9 = d
6 = d

Therefore, d = 6.

b) To solve for n in the equation n + 2 = -14 - n, we can start by adding n to both sides:
n + n + 2 = -14

Next, we can combine like terms:
2n + 2 = -14

Then, we can subtract 2 from both sides:
2n = -16

Finally, we can divide both sides by 2:
n = -8

Therefore, the solution is n = -8.

Answer 2

Explanation:

1 . ) 54 = 9d

54 / 9 = 9d / 9

d = 6

2 . ) n + 2 = - 14 - n

2n = - 16

n = - 8
