• Elimination would take fewer steps because you can add the equations to eliminate the y-terms and then you can divide both sides by 10 to find the value of x.

• The system of linear equations has exactly one solution, with a y-value of -3.

• Substitution would take fewer steps because you can change either equation to set it equal to y and then you can substitute the expression for y into the other equation.

• The system of linear equations has no solution.
