Question

What is the value of the y variable in the solution to the following system of equations?
3x - 6y = 12
-2x + 3y = 6

-14

24

14

-24

Answer 1

do you know how to solve these kind of problems?

Answer 2

not at all

Answer 3

ok first off try plugging in each # for the y value

Answer 4

Not 24

Answer 5

3x-6(-14)=12
then work it out
3x-(-84)=12
(-84)+12=13
3x=13
x=

Answer 6

x= 4.3333333333

Answer 7

A) 3x - 6y = 12
B) -2x + 3y = 6
Multiply equation B by 2
-4x + 6y = 12 and add this to Equation A
3x -6y = 12
-x =24
x = -24

3*-24 - 6y = 12
-6y = 12 +72
-6y = 84
y = -14
