Step-by-step explanation:
1) 90 --- 100%
x --- 20%
x = 90*20/100 = 18
2)
20 % = 20/100 = 0.2
20 percent (0.2) of (*) 90 = 0.2*90 = 18

Answer:
The system has no solution.
Step-by-step explanation:
Write the system as
y - 4x =3
2y - 8x = 3
The 2nd equation can be written as
2(y - 4x)
and the system would be
y - 4x =3
2(y - 4x) = 3
Now, call y -4x = z. Then we would have the system
z = 3
2z = 3
But if z =3 then 2z = 6 and we have a contradiction.
We conclude that the system has no solution.
