if x equals 4 what does why equal?
please help

  • maths - ,

    please

  • maths - ,

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

  • maths - ,

    thankyou so much i find them very hard

  • maths - ,

    You're welcome.

  • maths - ,

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

  • maths - ,

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

  • maths - ,

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

  • maths - ,

    y=1/2x - 1

    -3 = 1/2x - 1

    Add 1 to both sides of the equation.

  • maths - ,

    is it 0 or 2

  • maths - ,

    is it

  • maths - ,

    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 - ,

    i don't fully understand

  • maths - ,

    what sides do i double

  • maths - ,

    its ok i got the answer

  • maths - ,

    See -- we knew you could do it! :-)
