What is the first step in solving a system by Substitution?

• Make sure both equations are in standard form.

• Make sure at least one equation is solved for one variable.

• Make sure both equations are in slope-intercept form.

• Make sure both equations can be solved.

If (x,y) is a solution to the System of Equations above, what is the value of x/y(x divided by y)?

• Infinitely many solutions

• (3,-7)
  

• (5,9)

• No solution

Solve using the substitution method:

y = 3 - x

3y + x = 5

• No solution

• (1, 2)

• (3, 0)

• (2, 1)
