Solve simultaneous equation

X-2y=1

2x-y=2

Answer: x=1, y=0

Step-by-step explanation:

X-2y=1 ... equation 1

2x-y=2 ... equation 2

X=1+2y ... equation 3

Substitute equation 3into 2

2 (1+2y) - y=2

2+4y-y=2

2+3y=2

3y=2-2

3y=0

Y=0/3

Y=0

Substitute for y=0 in equation 1

X-2y=1

X-2 (0) = 1

X-0=1

X=1

X=1 & Y=0

x=1

y=0
