6x+5y=20 solve for y in terms of x

e-lub [12.9K]

Answer:

y = -6/5x +4

Step-by-step explanation:

6x+5y=20

Subtract 6x from each side

6x -6x+5y=20 -6x

5y = 20 -6x

Divide each side by 5

5y/5 = 20/5 -6x/5

y = 4 - 6/5x

We usually write the variable first

y = -6/5x +4

Give a direct proof for each of the following statements about the integers.

kkurt [141]

Answer:

See explanation below

Step-by-step explanation:

If x is even, then we know that x = 2k for a k ≥1

If y is odd, then we know that y = 2j -1 for a j≥1

Therefore, x + y can be written similarly as:

$x+y$

$2k +(2j-1)\\2(k+j)-1$

And clearly, 2(k + j) -1 is odd.

Therefore, the sum x + y is an odd number.
