Which expression is the simplest form of -(4x + y)n + 2(x - 3y)

Marina86 [1]

Answer:

$\boxed{\bold{-4nx-ny+2x-6y}}$

Explanation:

Rewrite:

= $\bold{-n\left(4x+y\right)+2\left(x-3y\right)}$

Expand $\bold{-n\left(4x+y\right): \ -4nx-ny}$

= $\bold{-4nx-ny+2\left(x-3y\right)}$

Expand $\bold{2\left(x-3y\right): \ 2x-6y}$

= $\bold{-4nx-ny+2x-6y}$

Using the problem below, solve and explain how you got the solution to the system of equation.

Paul [167]

Answer:

(5, -3)

y= -3

x= 5

Step-by-step explanation:

-x-2y=1

x+y=2

solve the equation

-x-2y=1

x=2-y

substitute the value of x into an equation

-(2-y)-2y=1

remove parenthesis

-2-y-2y=1

subtract y to 2y

-2-y=1

add 2 from both sides

-y=3

divide both sides by -y

y= -3

substitute the value of y into an equation

x=2-(-3)

remove parenthesis

x=2+3

add 2 to 3

x=5

----------

(5,-3)
