We are to find the probability that both your parents were born on weekend (either Saturday or Sunday).

Total number of days in a week = $7$

Number of days in weekend = $2$

Probability of being born on weekend = $\frac { 2 } { 7 }$

P (both parents were born on weekend) = $\frac{2}{7} \times \frac{2}{7}$ = 4/49

Solve the equation. Explain how you found your answer.<br><br> 8y + 2y = 2y + 40
