Question

2x + 5y = −3
−15x − 5y = −10
What method do you use to solve this and why? also can you explain step by step on how to solve the problem?

Answer 1

This is set up perfectly for the elimination method. Just add the 2 left sides to get a new left side and the 2 right sides to get a new right side.. You will then have one equation in one unknown, "x".

Answer 2

Second step, simplify that new equation and solve for "x". Third step, plug that value for "x" back into either equation and solve for "y".

And then you're done!

Answer 3
