Question

MEDAL AND FAN: PLEASE HELP ME!!!
What is the value of x in the solution to the following system of equations?
x − y = −3
x + 3y = 5

Answer 1

is this like graph wise?

Answer 2

or elimination

Answer 3

you could also eliminate one of the variables, so you can combine the two equations and solve for one variable.

Answer 4

x-y=-3
x+3y=5
So add -3+5
then eliminate the x's
u have left:
-y and 3y with 2
sp add them up 4y=2 and u got the rest

Answer 5

and thats the x part

Answer 6

well you could multiply the entire top equation by -1 and then add the top and bottom equations. for instance you would have -x+x = 0. meaning x would cancel ou.t
