What is the solution to the system?

What are some problems with solving by graphing?

If a system of linear equations has infinitely many solutions, what does this mean about the two lines?

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

How many solutions will this system have?

What is the solution to this system?

Solve the following systems of equations using substitution:

x = 6

y = 2x - 3

Solve the following systems of equations using substitution:

5x - 2y = 3

y = 2x

Solve the equation from the video:

y = x + 8

4x - y = -2

Solve the System of Equations by Substitution

y = 5x + 6

-3x + 4y = 7

Solve:

y = 7x + 9

2y + 4x = -18

Solve the system of equations by substitution (hint: both equations are equal to y, set them equal to each other and solve for x).

y = -4x + 5

y = 3x - 16
