Question

What is the value of x in the solution to the following system of equations?

x − y = −3
x + 3y = 5

Answer 1

-1

Answer 2

y=x-3

x+3(x-3)=5
x+3x-9=5
4x-9=5
4x=14
x=3.5

then solve for y

Answer 3

3x-3y=-9
x+3y =5

add it for the x
4x=-4
x=-1

Answer 4

@tim538 That is wrong. y should be equal to "y= x+3" not "y= x-3"

Answer 5

sorry your right
