multiply 140 to Frist equation and 5 to second equation then you get 'b' value substitute in any one of the above equation you get 'a' value

i mean not that answer
it
but i said that how 140 come
actually to make the equation convenient to solve easily we multiply with 140 to eqn 1 then it become 700a and we multiply 5 to eqn 2 then it will also become 700a so by this we can get value of one letter first
i know that but i am not talking about this own
