Fill in the missing value:
?(2x+y)=6x+3y
To solve this problem, we need to equate the expression ?(2x+y) to 6x+3y and solve for the missing factor.
Step 1: Analyze the expression 6x+3y.
- Notice that both terms, 6x and 3y, have a common factor of 3.
Thus, we can factor the expression as 3(2x+y).
Step 2: Equate the factored form 3(2x+y) with the original form ?(2x+y).
- If ?(2x+y)=3(2x+y), then the missing factor ? must be 3.
Therefore, the missing number that satisfies the equation ?(2x+y)=6x+3y is 3.
