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)
