Answer:

x = \frac{1}{5} , y = 6

Step-by-step explanation:

5x + y = 7 → (1)

20x + 2 = y → (2)

Substitute y = 20x + 2 into (1)

5x + 20x + 2 = 7

25x + 2 = 7 ( subtract 2 from both sides )

25x = 5 ( divide both sides by 25 )

x = \frac{5}{25} = \frac{1}{5}

Substitute this value into (2) and evaluate

20(\frac{1}{5} ) + 2 = y

4 + 2 = y , so

y = 6

Butoxors [25]

Answer:

Riley rakes 1/4 of the lawns per hour.

Step-by-step explanation:

In 1 hour Riley rakes \dfrac{1}{6}\times \dfrac{3}{2}=0.25 = 1/4 of a lawn.

Hence, Riley rakes 1/4 of the lawns per hour.
