Explanation Consider the system of equation { 2 x − y = 2 4 x + y = 3 . The solution of the system using the substitution method is as follows. To apply the substitution method, begin by using one of the equations to express one variable in terms of the other. Solve the equation 2 x − y = 2 for y , to express the variable y in terms of x as follows. 2 x − y = 2 y = 2 x − 2 Substitute 2 x − 2 for y in the second equation 4 x + y = 3 and solve for x as follows. 4 x + y = 3 4 x + ( 2 x − 2 ) = 3 4 x + 2 x − 2 = 3 Removing parentheses 6 x − 2 = 3 Collecting like terms on the left Solve the above equation further by adding 2 on both sides. 6 x − 2 + 2 = 3 + 2 6 x = 5 6 x 6 = 5 6 Dividing by 6 on both sides x = 5 6 Use back-substitution to find the value of y by substituting 5 6 for x in either of the original equations. Substitute 5 6 for x in first equation 2 x − y = 2 and solve for y as follows: 2 x − y = 2 2 ( 5 6 ) − y = 2 5 3 − y = 2 5 3 − y − 5 3 = 2 − 5 3 Subtracting 5 3 on both sides Simplified further as, 5
