Correct Answer
Explanation
To solve this system of equations,
we can use algebraic methods.
Here's how you can solve for x in the given system of equations:
First, we start with the equation x * 9 = (x + 10) * 6.
We can simplify this equation by combining like terms on the right-hand side, which gives us
x * 9 = 6x + 60.
Now we can subtract 6x from both sides of the equation to get 3x = 60.
Dividing both sides of the equation by 3 gives us x = 20.
So, the solution to the system of equations is x = 20.
