Final answer:
To simplify the given expression, (144y + y) becomes 145y, and (455x × 2) becomes 910x. The simplified expression is 145y - 910x.
Step-by-step explanation:
To simplify the expression (144y + y) - (455x × 2), we need to combine like terms and perform the subtraction operation in the parentheses. First, we combine the y terms:
144y + y = 145y
Next, we process the subtraction by multiplying 455x with 2, which gives us:
455x × 2 = 910x
Now, we subtract 910x from the previously obtained term:
145y - 910x
The expression is now simplified to two terms: one with the variable y and one with the variable x.
