Question

what is the value of x when -3x + 9 = -18

Answer 1

what is the value of n? 13 - 2n = -109

Answer 2

To solve the equation \(-3x + 9 = -18\), follow these steps:

1. Subtract 9 from both sides of the equation:
\[
-3x + 9 - 9 = -18 - 9
\]
This simplifies to:
\[
-3x = -27
\]

2. Now, divide both sides by -3:
\[
x = \frac{-27}{-3}
\]
This simplifies to:
\[
x = 9
\]

Thus, the value of \(x\) is \(9\).

Answer 3

To solve the equation \(13 - 2n = -109\), follow these steps:

1. Subtract 13 from both sides:
\[
13 - 2n - 13 = -109 - 13
\]
This simplifies to:
\[
-2n = -122
\]

2. Now, divide both sides by -2:
\[
n = \frac{-122}{-2}
\]
This simplifies to:
\[
n = 61
\]

Thus, the value of \(n\) is \(61\).
