Solving Linear Systems of Equations 6th 8.8

What is the solution?

• (1, -1)

• (-1, 1)

• (0, -2)

• (0, 1)

• So easy a 5th grader can do it, but I am a 6th grader and I cannot do it

Solve for x and y

3x + 2y = 16

7x + y = 19

• (-2,5)

• (-2,-5)

• (2,-5)

• (2,5)

• None of these. . . ????

If a system of linear equations has one solution, what does this mean about the two lines? 

• Parallel lines
• the same line 
• Intersecting lines
