8x + 5y = 27.15
what is x and y?

Step-by-step explanation:

Simplifying

8x + 5y = 27.15

Solving

8x + 5y = 27.15

Solving for variable 'x'.

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

Add '-5y' to each side of the equation.

8x + 5y + -5y = 27.15 + -5y

Combine like terms: 5y + -5y = 0

8x + 0 = 27.15 + -5y

8x = 27.15 + -5y

Divide each side by '8'.

x = 3.39375 + -0.625y

Simplifying

x = 3.39375 + -0.625y

Infinite solutions

Step-by-step explanation:

There is no one right answer, plug in numbers for x and you will see

y = -8/5(x) + 27.15/5

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
