Question

Solve the simultaneous equations.
You must show all your working.
y =x/2
2x-y=1​

Answer 1

Y=x/2
Now, putting the value of y in the second equation
2x-x/2=1
3x/2=1
3x=2
X= 2/3
Now putting the value of x in first equation
Y= (2/3)/2= 2/3*1/2= 1/3

Answer 2

Answer:

2x-y=1

2x-x/2=1 (y=x/2)

4x-x=2

3x=2

x=2/3

now,

y=1/3
