Answer:
Step-by-step explanation:
y = -6x + 12................. 1
-y + 3x = 6 .................2
from equation equation 1
y = -6x + 12................. 1
put y = -6x + 12
in equation 2
-( -6x + 12) + 3x = 6
6x - 12 + 3x = 6
6x - 3x = 6 + 12
3x = 18
divide both sides by 3
x = 6
to find y now
put x = 6 in equation 1
y = -6x + 12................. 1
y = -6(6) + 12
y -36 + 12
y = -24
therefore x = 6 y = -24
