Answer:

The sum of (−3x−4y) and (x+3y) in simplest terms will be:

[tex]\left(-3x-4y\right)+\left(x+3y\right)=-2x-y[/tex]

Step-by-step explanation:

Given

  • (−3x−4y)
  • (x+3y)

Finding the sum of (−3x−4y) and (x+3y)

[tex]\left(-3x-4y\right)+\left(x+3y\right)[/tex]

[tex]=-3x-4y+x+3y[/tex]

[tex]=-3x+x-4y+3y[/tex]

[tex]=-2x-4y+3y[/tex]

[tex]=-2x-y[/tex]

Therefore, the sum of (−3x−4y) and (x+3y) in simplest terms will be:

[tex]\left(-3x-4y\right)+\left(x+3y\right)=-2x-y[/tex]
