1.) Solve by substitution. What is the solution set?

3x +12y = 3

x= 8-4y

2.) Solve the following system of equations by graphing. If the system is inconsistent or the equations aredependent, say so. What is the solution set? (Draw a graph)

8x-5y = 3

16x-10y = 6

3.)Use the elimination method to solve the following system of equation. What is the solution set?

x+y = 6

x+y = -3

4.) Withoutgraphing, answer the questions for the following linear system.

6x+5y = 1

48x+40y = 9

(a) Is the systeminconsistent, or are the equationsdependent, orneither?

(b) Is the graph a pair of intersectinglines, a pair of parallellines, or oneline?

(c) Does the system have onesolution, nosolution, or an infinite number ofsolutions?

5.) Solve the following system by the elimination method. Check the solution. What is the solution set?

5x - 9 = -7y

6x +5y = -13

6.) Withoutgraphing, answer the questions for the following linear system.

x+5y = 0

30y = -6x

(a) Is the systeminconsistent, or are the equationsdependent, orneither?

(b) Is the graph a pair of intersectinglines, a pair of parallellines, or oneline?

(c) Does the system have onesolution, nosolution, or an infinite number ofsolutions?
