- Consider 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_forwardExplain the steps for solving a system of equations using Cramer’s rule.arrow_forwardUse 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_forward
- In Exercises 23 and 24, solve the system of equations in Exercises 21 and 22 by using algebraic methods. Refer to Exercise 21. 4x-3y=-3 x+2y=13arrow_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. x=22x+y=33x4y+z=10arrow_forward
