Question

PLEASE HELP?


What is the value of the y variable in the solution to the following system of equations?
3x + 2y = 6
2x + 3y = −6

answer choices:

6

−3

3

−6

Answer 1

one way would be to solve each equation for x; and see if the y values give the same x solutions

Answer 2

I dont get what you mean @amistre64

Answer 3

the others methods like substitution and elimination work also ..

Answer 4

if the y values you have for answer choices is true; it will produce the same x value in each equation; just trial and error it

Answer 5

lets try that y=6

3x + 2y = 6
3x + 2(6) = 6
3x + 12 = 6
3x = -6
x = -2

2x + 3y = −6
2x + 3(6) = −6
2x + 18 = -6
2x = -24
x = -12

since -2 is not the same as -12; we know 6 is not a correct choice
