Question

Add. Use models if needed. (4x – 12) + (–x + 7)

Answer 1

After adding $(4x-12) + (-x + 7)$ we get $3x-4$

Step-by-step explanation:

We need to add the following expressions.

$(4x-12) + (-x + 7)$

For addition we need to combine the like terms.

$(4x-12) + (-x + 7)\\=4x-12-x+7\\=4x-x-12+7\\=3x-4$

So, after adding $(4x-12) + (-x + 7)$ we get $3x-4$
