y = [(1/2) * 4]  1
y = 2  1
y = 1

maths  Ms. Sue, Thursday, February 24, 2011 at 11:44am
I showed you how to do the first one. You try this one; I'll be glad to check your answer.

maths  chloe, Thursday, February 24, 2011 at 11:48am
but im not sure can you show me you don't need to tell me the answer

maths  Ms. Sue, Thursday, February 24, 2011 at 11:51am
y=1/2x  1
3 = 1/2x  1
Add 1 to both sides of the equation.

is it 0 or 2

maths  chloe, Thursday, February 24, 2011 at 11:58am
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

maths  chloe, Thursday, February 24, 2011 at 12:04pm
i don't fully understand

maths  chloe, Thursday, February 24, 2011 at 12:10pm
