HW = 363: 1 – 25 odd.
We are solving equations here. Remember that you want to get the variable alone, and to do that, you have to remove the numbers that are with that variable. You remove the numbers by applying the opposite operation to both sides of the equation and doing that in the reverse order of operations (SADMEP)
so, if 3x+6 = 30, then you would have to first subtract six from both sides, and then divide both sides by three because subtraction and division are the opposite operations of multiplication and addition.
Howdy!
Attached is a review sheet for our test on Friday. Also attached are our notes from today and the full review of this unit. Come see me if you need help, and don’t forget that you CAN use IXL to study too.
Don’t forget the homework too! 391: 1 – 16 all.

Remember that we are interested in what 1x equals. So, use the opposite operation to make 1x. For example, if 3x=12, then I would divide each side by 3 because 3x/3 is 1x.
349: 4 – 36 even, plus 40 and 42. You must show all of your work.
Notes attached.
Remember . . . isolate the variable by adding and subtracting the numbers WITH the variable to make ZERO. And whatever you do to one side of the equation you have to do to the other side to keep the equation balanced and equal.
