Ms. Sue
y = [(1/2) * 4] - 1
y = 2 - 1
y = 1
y = 2 - 1
y = 1

thankyou so much i find them very hard
Ms. Sue
You're welcome.
chloe
sorry can i ask you one more question related to that one if y=-3 what is the value of x
Ms. Sue
I showed you how to do the first one. You try this one; I'll be glad to check your answer.
chloe
but im not sure can you show me you don't need to tell me the answer
Ms. Sue
y=1/2x - 1
-3 = 1/2x - 1
Add 1 to both sides of the equation.
-3 = 1/2x - 1
Add 1 to both sides of the equation.
chloe
is it 0 or 2
chloe
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
If you do as MsSue suggested, you should get
-2 = (1/2)x
Now double both sides for the value of x
chloe
i don't fully understand
chloe
what sides do i double
chloe
its ok i got the answer
Ms. Sue
See -- we knew you could do it! :-)
