10 If each equation below is solved for x, for which equation is x = 8 the solution?
Choose all that apply.
A 3x = 24
B 7x = 56
C 9x = 17
D 13 - X= 21
EX - 15 = -7
I know it’s A, B, and E For A you divide 24 by 3 For B you divide 56 by 7 And those both give 8 For C you divide 17 by 9 which isn’t 8. For D I think you’d subtract 13 from 21 which is 8 but then the equation is -x = 8 so to change x i think then it’d be x = -8 so I don’t think D is right but i’m not 100% sure
