hammers and wrenches are manufactured at a uniform weight per hammer and a uniform weight per wrench . if the total weight of two hammers and three wrenches is one - third that of 6 hammers and 5 wrenches , then the total weight of one wrench is how many times that of one hammer ?
"x be the weight of a hammer and y be the weight of a wrench . ( 2 x + 3 y ) = 1 / 3 * ( 7 x + 5 y ) 3 ( 2 x + 3 y ) = ( 7 x + 5 y ) 6 x + 9 y = 7 x + 5 y 4 y = x y = x / 4 ans - a"
divide(subtract(6, multiply(const_3, const_2)), subtract(multiply(const_3, const_2), 5))
