Question

11x-9=7x-9

Answer 1

To solve the equation \( 11x - 9 = 7x - 9 \), follow these steps:

1. First, get all the terms involving \( x \) on one side of the equation and the constant terms on the other side. You can do this by subtracting \( 7x \) from both sides:

\[
11x - 7x - 9 = -9
\]

This simplifies to:

\[
4x - 9 = -9
\]

2. Next, add \( 9 \) to both sides to isolate the term with \( x \):

\[
4x - 9 + 9 = -9 + 9
\]

This simplifies to:

\[
4x = 0
\]

3. Finally, divide both sides by \( 4 \):

\[
x = 0
\]

So, the solution to the equation \( 11x - 9 = 7x - 9 \) is \( x = 0 \).
