Question

How do you simplify 2(x+3y) -4x?

Answer 1

See a solution process below:

Explanation:

First, expand the term in parenthesis by multiplying each term within the parenthesis by the term outside the parenthesis:

`color(red)(2)(x + 3y) - 4x =>`

`(color(red)(2) xx x) + (color(red)(2) xx 3y) - 4x =>`

`2x + 6y - 4x`

Next, group like terms:

`2x - 4x + 6y`

Now, combine like terms:

`(2 - 4)x + 6y`

`-2x + 6y`
