Question

z=0 x=y x+y=2

Answer 1

What's the question?

Answer 2

solve the system?

Answer 3

yes please using planes find how to solve i seen it on some ones and it puzzeled me reposted my web page stoped

Answer 4

thing is... it is almost solved... just substitute the second equation into the third to find the other two variables...

Answer 5

2yea

Answer 6

so you got the solution?

Answer 7

no i wanted to see what solution i would need to put it in lol

Answer 8

subtract 2 from other side

Answer 9

the z coordinate is 0.
to get the x and y coordinates, notice that in the second equation, x=y.
substitute this into the third equation: x + y = 2 ---> x + (x) = 2

can you solve for x from here?

Answer 10

-2

Answer 11

x + x = 2
2x = 2
x = 1

can you solve for y? just substitute this value into the second equation...

Answer 12

ok i see but z=0?

Answer 13

z doesn't need to be solved because its value is already given
x=y; x+y=2
x+x=2 (since the value of x and y are the same, we can substitute x for y or the other way around)
2x=2
x=1; since x=y, y=1
check:
x=2-y (plug-in the values)
1=2-1
1=1
