Answer 2

5(2x-3y) = 4x + 6x - 4y = 4(2x-1) - 5

First, let's simplify the equation 5(2x-3y):

5(2x-3y) = 10x - 15y

Now, let's simplify the equation 4x + 6x - 4y:

4x + 6x - 4y = 10x - 4y

Now, let's simplify the equation 4(2x-1) - 5:

4(2x-1) - 5 = 8x - 4 - 5 = 8x - 9

So, the original equation can be written as:

10x - 15y = 10x - 4y = 8x - 9

Since 10x is equal to 10x, we can simplify the equation further:

-15y = -4y = -9

This equation does not make sense, as it states that -15y is equal to -4y, which is not possible. Therefore, the original equation is not solvable as it is written. It may be a typo or an error in the equation.
