Afirefighter uses equipment that weighs 60 pounds. the firefighter weighs x pounds. which equation can be used to find t, the total weight of both the fighter and his equipment. t= 60x t=x + 60 t=60-x t=x-60

For this case, the first thing we must do is define the variable x.
 We have then, that according to the statement of the problem:
 x = Weight of firefighter in pounds.
 We now write the equation that fits the problem.
 We have the following information:
 "a firefighter uses equipment that weighs 60 pounds." The firefighter weighs x pounds "
 Thus:
 t = x + 60
 
 An equation that can be used to find the total weight of both the fighter and his equipment is:
 t = x + 60
