Question

Part 1:
Solve the following system of equations. Please show your work to receive full credit.
x - y = 13
2x + y = 2

Part 2:
Explain which method you chose to solve the system and why you felt it was the best choice.

Answer 1

x=5
y=-8

Answer 2

@anuragtripathi what method did you use

Answer 3

add the two equations

Answer 4

after adding you will get

x+2x=13+2

3x=15

x=15/3

x=5

Answer 5

now put the value of x which is 5 in the first equation

5-y=13

shifting y to the right and 13 to the left

5-13=y

-8=y

Answer 6

i hope u get it

Answer 7

another (simpler) way of doing is to place it in 'y=mx+b' form.
graph it then determine where it intersects at. in this case its (5,-8)
