The first one is C. 68. The second one is B. 7. The third one is x = 21. The fourth one is CD = 10
-5y+8=-3y+10
-5y+3y=10-8
-2y=2
-2y/-2=2/-2
y=-1
I grouped the alike variable to one side, and the number to the other side, added and subtracted it, divided both sides by -2, and got -1
6x -19 + 3x + 10 = 180
9x -9 = 180
9x = 189
x = 21
It is 19 because 53 I know I was guessing Bc Idk Im annoying
