in the question, we have to solve the system of linear equations using microbes method. Where the questions are five X plus two Y supposed to four and seven X plus three miles goes to five. Now moving towards the solution from the given equation, the equation can be written as a. X equals to be So where the a matrix is the matrix with element 5 to 73 into the X metrics which is X. Y. Is supposed to be metrics 45 No, first we will be checking for the determinant of which comes out to be one that is not equal to zero. So the system of equations are consistent. Now moving further, we have to find X equals to invest in to be So As we know that the inverse is given by one by the determinant of micro oxy into the joint of A and two B. So now putting the values you will get X. Or it can be returned as X metrics is close to one x one of the a joint of A, which is my three minus two minus 75 into the matrix B. 45 So so long as you will get your X. Value S. Two and Y. Value S minus three. Thank you.
