What is the solution to the system of equations below?
noname [10]

Answer:

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)
