Solving Simultaneous equation using matrix method

Solving Simultaneous equation  using matrix  Method Question: Find the values of  x and y in the equations below 3 x + 2 y = 6 5 x − y = 8 Using matrix method Put the equations in standard form and then use matrices to solve the system of equations. 3 x + 2 y = 6 , 5 x − y = 8 Write the equations in matrix form ( 3 5 ​ 2 − 1 ​ ) ( x y ​ ) = ( 6 8 ​ ) Left multiply the equation by the inverse matrix of  ( 3 5 ​ 2 − 1 ​ ) . i n v e r s e ( ( 3 5 ​ 2 − 1 ​ ) ) ( 3 5 ​ 2 − 1 ​ ) ( x y ​ ) = i n v e r s e ( ( 3 5 ​ 2 − 1 ​ ) ) ( 6 8 ​ ) The product of a matrix and its inverse is the identity matrix ( 1 0 ​ 0 1 ​ ) ( x y ​ ) = i n v e r s e ( ( 3 5 ​ 2 − 1 ​ ) ) ( 6 8 ​ ) Multiply the matrices on the left hand side of the equal sign. ( x y ​ ) = i n v e r s e ( ( 3 5 ​ 2 − 1 ​ ) ) ( 6 8 ​ ) For the  2 × 2  matrix  ( a c ​ b d ​ ) , the inverse matrix is  ( a d − b c d ​ a d − b c − c ​ ​ a d − b c − b ​ a d − b c a ​ ​ ) , so the matrix equation can be ...

Arithmetic Progression

How to calculate the common difference when the first term and the nth term is know.  Question: The 28th term of an AP is -5. Find the common difference if its first term is 31. Solution T1 = a ( First term of the sequence) a = 31 T28 = -5 (28th term of the sequence) d = ? (common difference) Recall the nth term formula of Ap i.e  Tn = a + (n-1)d        Substitute 28 for n to get the following equation        T28 = a + (28-1)d          T28     = a + 27d        Substitute T28 for -5 and 31 for a  in the equation above               -5     = 31 + 27d          Subtract 31 from both sides of the equation         -5 -31 = 27d          -36 = 27d        Divide through by 27        -36/27  =  27d/27 ...
