3x + 2y = -3
Which equivalent equation could be used?
Answers
Solve the first equation for "y" and you get: y = 2x - 5.
That is the equivalent equation that answers the question.
To solve the system, you substitue it for "y" in the second equation and you obtain:
3x + 2 (2x - 5) = -3
Now you have one equation with one single variable, "x" which you can solve easily.
Please, let me know if you could follow the explanation.
