Solve the system by using Cramer’s Rule.
[Hint: Do not try to simplify the equations by clearing the denominators because the resulting equations will not be linear. Instead, let

- Use Cramers Rule to solve the system of linear equations for x and y. kx+(1k)y=1(1k)x+ky=3 For what values of k will the system be inconsistent?arrow_forwardConsider the system of linear equations in x and y. ax+by=ecx+dy=f Under what conditions will the system have exactly one solution?arrow_forwardUse Gaussian elimination to find the complete solution of the system, or show that no solution exists. {2x3y+z=3x+2y+2z=14x+y+5z=4arrow_forward
- Solve using Cramer’s rule. 414. {3x+y=32x+3y=6arrow_forwardThe systems in Exercises 25 and 26 exhibit a lower triangular pattern that makes them easy to solve by forward substitution. (We will encounter forward substitution again in Chapter 3.) Solve these systems. x1=112x1+x2=532x1+2x2+x3=7arrow_forward
