Answer:
x = 2
y == -1
Step-by-step explanation:
Solving linear equations by elimination method:
x - 10y = 12 ----------------(I)
10x + 10y = 10 --------------(II)
We can find the value of 'x' by eliminating 'y'. To eliminate 'y', add equations (I) & (II)
(I) x - 10y = 12
(II) 10x + 10y = 10 {Now add the equations}
11x = 22
x = 22 /11

Now, Plugin x = 2 in equation (1)
10*2 + 10y = 10
20 + 10y = 10
10y = 10 - 20
10y = -10
y = -10/10
[tex]\sf \boxed{\bf y = -1}[/tex]
