11 + 19x = 49
19x = 49 - 11
19x = 38
x = 38/19
x = 2 <== 2 products are being purchased
because she picked out 2 products...which took (19 * 2) = 38 seconds....and then it took another 11 seconds at the checkout....so thats a total of (38 + 11) = 49 seconds

Answer:
Part 1) The team lost 70 games
Part 2) The team played 154 games
Step-by-step explanation:
Part 1)
Find the number of games lost
Let
x -----> number of games won
y -----> number of games lost
we know that
x=y+14 -----> equation A
x=84 ----> equation B
Substitute equation B in equation A and solve for y
84=y+14
subtract 14 both sides
84-14=y
70=y
Rewrite
y=70 games lost
Part 2) How many games did they play?
To find out how many games were played, add the games won and the games lost
so
x+y=84+70=154 games
