Solve the system of equations using substitution, elimination by addition, or augmented matrix methods (your choice). show work. 5x - 3y = 11 7x + 4y = -1

 The required solution is  x = 1  and  y = -2.

Step-by-step explanation:  We are given to solve the following system of equations using substitution, elimination by addition or augmented matrix methods :

We will be using the method of SUBSTITUTION to solve the given system.

From equation (i), we have

Substituting the value of x from equation (iii) in equation (ii), we get

Putting the value of y in equation (iii), we get

Thus, the required solution is  x = 1  and  y = -2.
