    With workings please!
    4x+5(-5)=x+26(-5)
    4x=x+21
    4x(-x)+x+21(-x)
    3x=21
    Divide both sides by 3
    21/3=7
    3x/3=x
    X=7

    No. You will notice that I added with workings. This is so I can follow it and can learn how to work it out.

    Ok so to work out the value of x in this linear equation, you need to get all the x values on one side of the equal side and other numbers on the other side of the equal sign.

    You can do this by adding and subtracting x from the right and then subtracting it from the left.

    You can the subtract 5 from the right which means that you will need to subtract it from the right aswell.

    This would leave you with 3x = 21

    So now you should be able to solve for x easily
    Thumbs up would be appreciate if it helped!
