What is the solution to the system of equations below?

Negative 4 x + 6 y = negative 18 and y = negative 2 x + 21

(9, 3)

(3, 9)

(-9, - 9)

(-9, 9)

solution: (9, 3), x = 9, y = 3

Step-by-step explanation:

Negative 4 x + 6 y = negative 18 and y = negative 2 x + 21

convert to algebra.

- 4x + 6y = - 18;

y = - 2x + 21;

let us solve this with elimination

change - 4x + 6y = - 18 to - 2x + 3y = - 9

get: - 2x + 3y = - 9

and 2x + y = 21

add.

-2x + 2x + 3y + y = - 9 + 21

4y = 12

y = 3

2x + (3) = 21

2x = 18

x = 9

(9, 3)
