Answer:
e ^1/2
Step-by-step explanation:
All you do is take the fraction (4/8) and just simplify that part
4 divided by 2 = 2
8 divided by 2 =4
I got 2/4 but I can simplify more
2 divided by 2= 1
4 divided by 2 = 2
Now I got 1/2
And I would just leave e alone so my answer is e ^1/2
Do you kinda get what im saying?

Answer:
x=1, y=3
Step-by-step explanation:
21x + 7y = 42
Divide this by 7
3x +y = 6
-5x +5y = 10
Divide this by 5
-x+y = 2
Subtract the two equations to eliminate y
3x +y = 6
-(-x+y = 2)
------------------------
3x +y = 6
+x-y = -2
------------------------
4x = 4
Divide by 4
x = 1
Now solve for y
-x+y = 2
-1 +y = 2
Add 1 to each side
y = 2+1
y =3
