Mathematics

Answer:

x = \frac{4}{5}, y = \frac{1}{5}

Step-by-step explanation:

Express as 2 equations, that is

x + y = 1 → (1)

- x + 9y = 1 → (2)

Add the 2 equations term by term to eliminate x, that is

10y = 2 ( divide both sides by 10 )

y = \frac{2}{10} = \frac{1}{5}

Substitute this value into (1) and solve for x

x + \frac{1}{5} = 1 ( subtract \frac{1}{5} from both sides )

y = \frac{5}{5} - \frac{1}{5} = \frac{4}{5}
