What's the answer?...

Simplifying

0.5x + -2y = 6

Solving

0.5x + -2y = 6

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2y' to each side of the equation.

0.5x + -2y + 2y = 6 + 2y

Combine like terms: -2y + 2y = 0

0.5x + 0 = 6 + 2y

0.5x = 6 + 2y

Divide each side by '0.5'.

x = 12 + 4y

Simplifying

x = 12 + 4y

Step-by-step explanation:

(y=3/8x+2)

.5x-2(3/8x+2)=6

.5x-3/4x-4=6

1 1/4x=10

x=8

3(8)+8y=16

24+8y=16

8y=-8

y=1

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
