Short Answer: x=5 y=6 Explanation: For x you do 7-2 (because in the equation you add so do the opposite) that equals 5 which is your answer. For y you have to get all the y's on one side so this is how i done it: 2y+1=y+7 2y=y+6 (there's a plus 1 on the other side so i need to subtract it to get it to zero, what you do to one side you do to the other) y=6 ( there's one y on this side so i take it away from both leaving the answer) Hope that helped =)

is your problem: -|4-27| ? if so, first eval the expression inside the abs value and get -23 then |-23|=23, and finally -|-23| = -23, which is the final result

I believe what your are asking is this: -| 4 - 27 | So what you do is solve whats inside, which is 4 - 27 = -23. Then you take the absolute value of it which is just positive 23, but since there's a negative outside of it, it makes the number -23.
