A quarterback throws 50 passes in one game.  He throws twice as many passes to the right of the field than he does to the left of the field.  He throws 2 more passes to the center of the field than he did to the left.  How many passes did he throw to the left side of the field?
Define a variable ** Let x represent the number of passes thrown to the left side of the field
How many passes are thrown to the right side? ** Right:2x
How many passes are thrown to the center? ** Center:x+2
Write an equation ** Total:x+2x+x+2=50
Combine like terms ** 4x+2=50
Subtract 2 from both sides ** 4x=48
Divide by 4 ** x=<<12=12>>12 passes
