Select all expressions that are equivalent to 4x+2(2x-5)-(3-5x)

Arada [10]

For this case we have the following expression:

$4x + 2 (2x-5) - (3-5x)$

Applying distributive property to the terms within parentheses taking into account that:

$- * + = -\\- * - = +$

We have:

$4x + 4x-10-3 + 5x =$

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

$4x + 4x + 5x-10-3 =\\13x-13$

Thus, an equivalent expression is:

$13x-13$

Answer:

$13x-13$
