    Yes, Algebra I, Algebra II, Calculus? You must be specific when asking questions, okay? :)

    Well I don tknow what it is but here's the problem. C/5.3+8.3=11.3

    C could stand for Circumference, or a variable among other things. I'll see what I can do. Let's assume C is a variable.

    \[35 = -5 + (2x - 7x) \] Use the substitution method.

    35 = -5 + (2x - 7x) 35 + 5 = -5x 40 = -5x -40/5 = x -8 = x

    I was too slow. x = -8. Yep. ;)

    Who cares if you were slow? You do things systematically and that's great! :)

    Lol ya. Thank you. Sorry, I need help with this one too. -1.2= z/4.6-2.7

    Linear equations. I never liked these. \[-1.2 = (z) / (4.6 - 2.7) \]\[z \approx -2.28\] It's really helpful if you use a linear plane.

    -1.2 = z/1.9 -1.2*1.9 = z -2.28 = z is your final answer.

    Would you like to write equations? At the bottom of the reply box, there are four buttons. Equation - Draw - Attach File - Post. Click the Equation button and type your problem in. Hit enter. \[10 = 2/(7n + 4)\]

    \[10 = 2/(7n+4) \]\[6 = (2/7n)\]\[(7/2)2/7n = (7/2)6 \]\[n = 21 \]
