Question

Part 1: Decide whether you would use the graphing, substitution, or elimination method to solve the following system of equations. Explain, in complete sentences, why you chose that method.
Part 2: Solve the following system of equations and show all of your work.

2x + 5y = −3
−15x − 5y = −10

Answer 1

add equation 1 and 2
5y will get canceled
you will get value of x
then find y

Answer 2

that's elimination method

Answer 3

The coefficients of y have equal magnitude and opp sign,...so elimination

Answer 4

after adding
you will get -13x=-13
so x=1
put it in equation 1
you will get 5y=-5
so y=-1
