Explanation:
The expression 5x + 6y - 3x is equivalent to:
2x + 6y
This is because 5x and -3x can be combined by adding them together, which gives 2x.
The expression 5x + 6y - 3x is also equivalent to:
x + 6y - 3x
This is because 5x and -3x can be combined by adding them together, which gives x.
However, the expression 5x + 6y - 3x is not equivalent to:
2x - 3y
This is because the coefficient of the y term is 6, not -3.
The expression 5x + 6y - 3x is also not equivalent to:
x + y
This is because the coefficient of the y term is 6, not 1.
