Question

fill in the boxes to write an expression equivalent to $2x + 5y - 3y + 4x$.

Explanation:

Step1: Combine like terms for x

We have \(2x + 4x\). Combining these, we get \((2 + 4)x = 6x\).

Step2: Combine like terms for y

We have \(5y - 3y\). Combining these, we get \((5 - 3)y = 2y\).

Step3: Factor the expression

Now we have \(6x + 2y\). We can factor out a 2 from both terms: \(2(3x + y)\).

Answer:

The first box is 2 (already given), the second box should be 3, so the expression is \(2(3x + y)\). So the number in the second box is 3.
