Question

What is the result of adding these two equations? 6x + 2y = -2 3x – 2y = -5

Answer 1

Answer:

x=-7/9

y = 12/9

Step-by-step explanation:

6x + 2y = -2

3x - 2y = -5

9x = -7 (-2y and +2y eliminated)

x = -7/9

if 3x -2y = -5 then

3 ×(-7/9) -2y =-5➡

-21/9 -2y = -5➡

-2y = -5 + 21/9

-2y = -24/9

Answer 2

Answer: 9x=-7

Step-by-step explanation:

Line up the 2 equations like when you add( one on top of the other)

6x+2y=-2

3x-2y=-5

Your going to add the number from the top and add the number directly below it

That would give you

6x+3x = 9x

2y + (-2y)=0 do not put 0 just leave it blank

they cancel each other out since the number is the same but one is negative and the other is positive

-2 + -5=-7

Finally bring put the answers you got together in the corresponding order according to the equation and bring down the equal sign

Final answer:

9x=-7
