By substitution Repalce the value of x in first equation: 4.4 y + 4y = 6 8.4y = 6 y = 6/8.4 = 1/1.4 Multiply both numeratoy and denomenator by 5 to get the answer 5/7 y = 5/7 To find x: Replace y as 5/7 in the first equaton: x + 4y = 6 x + (4 x 5/7) = 6 x
Running 1hour = 8 miles 1.5 hors = 8 x1.5 = 12 miles Bus 60 minutes = 55 miles 24 mins = ? 24/60 x 55 = 22miles total = 12 + 22 =34 miles.
