Question

anonymous · Answer

Need more equations haha

anonymous · Answer

x - y = 10
2x + y = 2

anonymous · Answer

Add the two equations to get 3x=12
x=4
Plug x back in, 2(4) +y=2
y=-6

x=4 y=-6

Elimination and substitution.

anonymous · Answer

elimination method
add the equation eliminates y 
so u solve for x
and then find y by plug in y in 1st equation

anonymous · Answer

edge has done the algebra

anonymous · Answer

Ok Hold on... Edge. can you elaborate on add the two equations?

anonymous · Answer

x - y = 10
2x + y = 2

adding  -y + y = 0  so y disappears

you get
3x + 0 = 12
x = 4

anonymous · Answer

What jimmy said

anonymous · Answer

Ok Then What?

anonymous · Answer

plug x=4 in x - y = 10
so
4 - y = 10
-y = 10 - 4 = 6
y = -6
