Solve the system of linear equations using the substitution method.
3x + 3y = 0
6x + 9y = 10

Algebra 
Ashley Kate,
My answer to the above system is (2/3, 2/3). Am I right?

Algebra 
Damon,
x + y = 0
so
y =  x
then
6 x + 9 (x) = 10
 15 x = 10
x = 2/3
then
y =  x = 2/3
So Yes 
Algebra 
Ashley Kate,
Thanks
