The simplified expression is -30x + 720y.
To simplify the expression 28x + 310y - 58x + 410y by combining like terms, you need to combine the coefficients of the same variables.
Combining the x terms, you have 28x - 58x = -30x.
Combining the y terms, you have 310y + 410y = 720y.
So, the simplified expression is -30x + 720y.
To simplify the expression by combining like terms, you need to add or subtract the coefficients of terms that have the same variables raised to the same powers.
Let's simplify the expression step by step:
Start with the given expression: 28x + 310y - 58x + 410y
First, combine the terms with the variable "x":
28x - 58x = -30x
Next, combine the terms with the variable "y":
310y + 410y = 720y
Putting it all together, the simplified expression is: -30x + 720y
Therefore, the correct answer is: -30x + 720y
