How do you write #-3x-(-2-4x)# in standard form?

Answer 1

Genesis Allen

See the entire solution process below:

First, expand the terms within parenthesis. Be careful to handle the signs of the individual terms correctly:

#-3x + 2 + 4x#

Next, group like terms:

#4x - 3x + 2#

Now, combine like terms:

#(4 - 3)x + 2#

#1x + 2#

#x + 2#

To write -3x - (-2 - 4x) in standard form, you need to distribute the negative sign inside the parentheses and then combine like terms:

-3x - (-2 - 4x) = -3x + 2 + 4x

Now, combine like terms:

= (4x - 3x) + 2

= x + 2
