Question

5 (x-4) +3x - 9x + 7

step one: use the distrubutive property.
step two:use the commutative property of addition to reorder like terms that are together.
step three: use the associative property of addition to group like terms.
step four: simplify.

Answer 1

Explanation:

Step one: Use the distributive property

In this step, we distribute the coefficient outside the parentheses to each term inside.

5(x-4) = 5*x - 5*4

Step two: Use the commutative property of addition to reordering like terms that are together.

The expression becomes:

5x - 20 - 9x + 7

Step three: Use the associative property of addition to group-like terms.

We group together the x terms and the constant terms separately:

(5x - 9x) + (-20 + 7)

Step four: Simplify

We combine like terms within each group:

-4x -13
