In substitution method first of all you have to find the value of first variable for example take a as a first variable and B A second variable let the expression be to A + 5 b is equal to 6 Now possible find the value of a is equal to-5 b so put the value of stay in another equation and their you will find the value of B and then put the value of be in this occasion so you will get the value of a
