Answer 2

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
