Question

Solve the following system.
x − y = 10
x + y = 2

(6, −4)

(6, 4)

(−4, 6)

(−6, 4)
please this is kinda of confusing me here i need help

Answer 1

Argh this is confusing me too, give me a second.

Answer 2

Subtract each other

x-y=10
x+y=2

-2y=8
y=-4

Then put y back into one of the equations to solve for X

x-(-4)=10
x=6

or..

x+(-4)=2
x=6

So the answer is (6,-4)
