2(3x-4) = 5x+6 First, expand the bracket. 6x-8=5x+6 Next, move the variables to the same side. x-8=6 Move the -8 to the other side, change to + x=6+8 x=14 Charlie’s solution is incorrect. When expanding the bracket, he changed the - to a +.
I believe it would be addition property of equality since you can add 14 and 8 to recieve the number that the 8 is being subtracted from to get 14. So in this case x would equal 22.
Supplementary Angles: 180-83, so the answer would be A) 97 PQ Line Segment: You would just have to get a ruler and measure it. From the looks of it, EF looks like the answer
