System of Solutions by Substitution

How many solutions does the graph have?

• One solution

• No solution

• Infinite solutions

The first step in solving using the substitution method is __________.

• get x by itself

• get y by itself

• get either variable by itself

• add the equations together

^{What is the solution?} 

• 1

• -2

• (1, 2)

• (1, -1)

Using Substitution, solve for the system of linear equations: x=-3y+1 -3x-3y=-15
