Solve the system of equations by the addition method <br> { 5x-y=-3<br> { 4x+3y=-48
Svetach [21]

Answer:

(-3,-12)

Step-by-step explanation:

Multiply the first equation by three to match the second equations y-term

  • 3(5x-y=-3)
  • 4x+3y=-48

  • 15x-3y=-9
  • 4x+3y=-48

The y-terms cancel out

  • 15x=-9
  • 4x=-48

Add the x-terms with each other and the terms after the equal sign as well

  • 19x=-57

Divide -57 by 19

  • x=-3

Input your x-term (-3) into one of the two first equations and multiply

Either:

  • 5(-3)-y=-3 or
  • 4(-3)+3y=-48

  • -15-y=-3 or
  • -12+3y=-48

Simplify your terms

  • -y=12
  • 3y=-36

Divide

  • y=-12
  • y=-12

PLEASE MAKE SURE YOU GIVE WORKING AND AN EXPLANATION FOR YOUR ANSWER Question) The sum of the integers from -2015 to 2017 is (A)
yKpoI14uk [10]

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).
