Which is the best method to use?
−2x−3y=−7
Graphing
Substitution because a variable is isolated.
Elimination because both equations are in standard form.
Describe the error in solving the system of equations using elimination:
They eliminated the x terms when they should have eliminated the y terms.
The subtracted 5x and x to get 4x, but they should have added the x terms to get 6x = 24.
They added 16 and 8 to get 24, but they should have subtracted them to get 8 on the right side of the equation.
They eliminated the y terms, but they couldn't because one is a negative and one is a positive.
What is the best method do you use?
2x+5y=−21
−2x−3y=−7
Graphing
Substitution because a variable is defined
Elimination because both equations are in standard form.
