let b and g be the cost of one heavy bag and pair of gloves respectively, then
b + g = 1 1 5 ⟹ b = 1 1 5 − g ( 1 )
and
b = 2 g + 2 5 ( 2 )
Substitute ( 1 ) in ( 2 ) . we have
1 1 5 − g = 2 g + 2 5 ⟹ 3 g = 9 0 ⟹ g = $ 3 0

suppose, the cost of a pair of MMA gloves is= x
so, the cost of one heavy bag will be = 2 x + 2 5
now,
x + 2 x + 2 5 = 1 1 5
or, 3 x = 1 1 5 − 2 5
or, x = 3 9 0 = 3 0
