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
