    14-3(2x+3)=2

    Please can somebody walk me through how to solve this? I know the answer is 1/2 (I have the answers along with the workbook, but I would like to know how to solve it and get to that answer- just knowing the answer doesn't help me at all!)

    Thank you!

    If your algebra skills are not that great then probably the best general purpose approach to this kind of problem would be to expand the brackets. Then rearrange to solve for x.

    Solve the equation by rearranging the equation and solving from both sides. Basically just get rid of all that the jargon on the X side until you only have X left, so this means breaking down the equation into parts.
    So to start you off you can subtract 14 from both sides..

    This gives you

    -3(2x+3) = -12

    You can probably work out how to do the rest.

    Use BIDMAS. Expand the brackets first and then collect like terms. Solve for x after that.

    -3(2x+3)=-14+2 ----> -3(2x+3)=-12
    2x+3= -12/-3
    2x+3=4
    2x=1
    x=1/2

    XD hope this helped

    You need to rearrange it. As there is only one component you need that on one side:

    14-3(2x+3)=2

    12 = 3(2x +3)

    From there it should be pretty self explanatory but remember to use BIDMAS. If you need more help from there you can ask for it.

    Expand it


    14-3(2x+3)=2

    14 - 6x -9 =2

    14-6x = 11

    -6x = 11-14

    -6x = -3

    x=1/2



    Took me 15 seconds to do this
