this is urgent
y=1/2x  1
if x equals 4 what does why equal?
please help

please

y = [(1/2) * 4]  1
y = 2  1
y = 1 
thankyou so much i find them very hard

You're welcome.

sorry can i ask you one more question related to that one if y=3 what is the value of x

I showed you how to do the first one. You try this one; I'll be glad to check your answer.

but im not sure can you show me you don't need to tell me the answer

y=1/2x  1
3 = 1/2x  1
Add 1 to both sides of the equation. 
is it 0 or 2

is it

Neither 0 nor 2.
If you do as MsSue suggested, you should get
2 = (1/2)x
Now double both sides for the value of x 
i don't fully understand

what sides do i double

its ok i got the answer

See  we knew you could do it! :)
