Find the solution to this system of equations and write it as an ordered
pair (x, y) *
3x + 3y = -18
2x - 4y= -6

Answers

Answer 1

Answer:

Step-by-step explanation:

Simplifying

3x + 3y = -18

Solving

3x + 3y = -18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3y' to each side of the equation.

3x + 3y + -3y = -18 + -3y

Combine like terms: 3y + -3y = 0

3x + 0 = -18 + -3y

3x = -18 + -3y

Divide each side by '3'.

x = -6 + -1y

Simplifying

x = -6 + -1y

//////////////

Simplifying

2x + -4y = -6

Solving

2x + -4y = -6

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4y' to each side of the equation.

2x + -4y + 4y = -6 + 4y

Combine like terms: -4y + 4y = 0

2x + 0 = -6 + 4y

2x = -6 + 4y

Divide each side by '2'.

x = -3 + 2y

Simplifying

x = -3 + 2y

PLEASE MAKE SURE YOU GIVE WORKING AND AN EXPLANATION FOR YOUR ANSWER Question) The sum of the integers from -2015 to 2017 is (A) 2 (B) 2017 (C) 4033 (D) 6048

Answers

Answer:  (A) 2

The sum of the integers from -2015 to 2017  = 2

Step-by-step explanation:

The sum of integers a and b is represented as a+b.

The sum of the integers from -2015 to 2017  = -2015+2017

Since -a+b=b-a

Thus, The sum of the integers from -2015 to 2017  = 2017-2015 = 2

i.e.  The sum of the integers from -2015 to 2017  = 2

Thus , the correct option is (A).
