Change first equation
x - 2y = 1
add 2y to both side
x = 2y + 1
Plug into second equation
3(2y+1) - 6y = 3
Distributive property
6y + 3 - 6y = 3
y = 0, plug into first equation
x - 2(0) = 1, x = 1
Solution: x = 1, y = 0

the correct question in the attached figure

(2^5)/8=2^2

(2^5)/8----------- >  (2^5)/(2^3)=2^(5-3)=2^2

therefore 

2^2=2^2-- ------> is ok
