Question

What is the value of y in this system of equations?

Negative 6 x + 2 y = negative 18. Negative 3 x minus 2 y = 54.

Answer 1

Answer: -21

Explanation:

Answer 2

y = - 21

Explanation:

System of equations:

- 6x + 2y = - 18

- 3x - 2y = 54

To find y will look to eliminate x:

- 6x + 2y = - 18

- 3x - 2y = 54 (multiply both sides by -2)

- 6x + 2y = - 18

6x + 4y = - 108

---------------------------- (add those two equations)

6y = - 126 (divide both sides by 6)

y = - 126/6 (simplify by 6)

y = - 21
