Answer:
x = -3, y=2
Step-by-step explanation:
x+3y =3
3y -2x =12
Solve the first equation for x
x = 3-3y
Substitute this into the second equation
3y -2(3-3y) =12
Distribute
3y -6 +6y =12
Combine like terms
9y -6 =12
Add 6 to each side
9y-6+6 =12+6
9y =18
Divide each side by 9
9y/9 =18/9
y = 2
Now find x
x = 3 -3y
x = 3-3(2)
x = 3-6
x = -3
Answer:
x = -3 y = 2
Step-by-step explanation:
x + 3y = 3
2x - 3y = -12
3x = -9
x = -3

Calculate percentage change
from V1 = 14 to V2 = 40
(2−1)|1|×100
=(40−14)|14|×100
=2614×100
=1.85714×100
=185.714%change
