Amber coaches soccer and volleyball. she coaches both sports for a total of 7 hours each day. the soccer practice lasts 1 hour more than twice as long as the volleyball practice. write a system of equations to model the situation. use v for the number of hours amber coaches volleyball in a day and s for the number of hours she coaches soccer.

Amber coaches both sports for 7 hours each day

v = volleyball hours
s = soccerball hours

7 hours in total, in which soccerball is 1 hour more than volleyball:
v + s = 7
s = v + 1

plug in v + 1 for s

v + s = 7
v + (v + 1) = 7

simplify

v + v + 1 = 7
2v + 1 = 7
2v + 1 (-1) = 7 (-1)
2v = 6
2v/2 = 6/2
v = 6/2
v = 3

Plug in 3 for v for one of the equations.

s = v + 1
s = (3) + 1
s = 4

Amber coaches 3 hours for volleyball, and 4 hours for soccer, making a total of 7 hours

hope this helps
