Question

Negative x + 6y = 16 and 8x - 6y = -2 which statements about the system of equations are true check all that are apply the x variable will be eliminating when adding the system of equations and the y variable will be limited when adding the system of equations or the sum of the system equations is negative 8X = 14 or x = 2 or y = 3 or there's only one solution to the system equations

Answer 1

y variable will be elimited when adding the system of equations

x = 2 or y = 3

Explanation:

- x + 6y = 16

8x - 6y = -2

Add both equations

(-x + 8x) + {6y + (-6y)} = 16 + (-2)

7x + 6y - 6y = 16 - 2

7x + 0 = 14

7x = 14

x = 14/7

x = 2

- x + 6y = 16

- 2 + 6y = 16

6y = 16 + 2

6y = 18

y = 18/6

y = 3

the x variable will be eliminating when adding the system of equations and the

y variable will be elimited when adding the system of equations

or the sum of the system equations is negative 8X = 14 or

x = 2 or y = 3

or there's only one solution to the system equations
