Answers

A negative multiplied by a positive ALWAYS results in a negative. To make things simpler, you could multiply 12 by 3 to get 36, and then add on a negative afterwards. Otherwise, you can use your integer rules or a calculator. Any way you do it, the answer will be -36.

it would be -36 because a negative times by a positive is a negative

Solve the following system of equations.-2x + y = 1

B) (-1,3)
C) (-1,-3)
D) (1,3)

Hi Brainiac

-2x+y=1

-4x+y=-1

We need to solve -2x+y=1 for y

Now let's start by adding 2x to both sides

-2x+y+2x=1+2xy=2x+1

Substitute 2x+1 for y in -4x+y=-1

-4x+y=-1

-4x+2x+1=-1

-2x+1=-1

Add -1 to both sides

-2x+1-1=-1-1

-2x=-2

Now divide both sides by -2 so we can fine the value for x

-2x/-2= -2/-2

x=1

The last step is to substitute 1 for x in y=2x+1

y=2x+1

y=(2)(1)+1

y= 2+1

y= 3
