Solve the inequality. Show your work. 6y – 8 ≤ 10 This is what i got. Am i right or am i wrong? 6y -8 ≤ 10 -6y -6 -8 4 +8 12 y = 12 plug in 12 in place of the y 6+12 -7 ≤ 10 6+ 12 -7 is less then equal to 10

    Hmm.. your concept is correct, but here is the correct way to do it:

    |dw:1435874492127:dw| So in this step, you did -6y on both sides.. remember that you first need to subtract the single integer before doing anything to the coefficients.

    |dw:1435874558210:dw| It should have been set up like this then

    So i need to get rid of my negative number first?

    Even when you did "-6y" on both sides, you should have included your "y" with the 6.. you can't just get rid of y.

    No, you need to get rid of any number that doesn't have a variable with it.. regardless if it is negative or not.

    Now we need to isolate the y variable. Do you have an idea as to how to do that?

    Hint: Apply inverse operations to the left side of inequality.

    If it's not subtracting it, then no.

    |dw:1435874740349:dw| You need to divide my 6 on both sides so the y is by itself. Since it is 6 times y, dividing 6y by 6 would make it just y.

    If you do something to one side of the inequality, you must do it on the other, too.

    How did you get 18?

    10 + 8 = 18

    Yes.. but I need to apply INVERSE operations to GET RID of it.

    there is no point in doing "-8" again.. makes no sense

    18/6 = 3 So, y is less than or equal to 3.

    True didn't realize you added the 8 as part of the fraction.
