A system of equations is shown below. What statement is TRUE about the relationship between the value of k and the number of solutions for the system of equations? Hint: Plug in 21 for k and put both equations in slope-intercept form .
For any value of k, the system of equations has no solution.
For any value of k, the system of equations has infinitely many solutions.
If k is equal to any value other than 21, the system of equations has no solution.
If k is equal to any value other than 21, the system of equations has infinitely many solutions.

A system of linear equations is given below. Does it take fewer steps to determine the solution to the system of equations using elimination or substitution? What is the solution? (Select 2 answer options).
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.
