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

Answered by chloe
but im not sure can you show me you don't need to tell me the answer
Answered by Ms. Sue
y=1/2x - 1

-3 = 1/2x - 1

Add 1 to both sides of the equation.


Answered by chloe
is it 0 or 2
Answered by chloe
is it
Answered by drwls
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
