Answer:
243/4(x^12)
Step-by-step explanation:
81x^12 x 3/4 = 243/4(x^12)
(A)6x+4x-6=24+9x
10x-6=24+9x
10x-9x=24+6
x=30. (only 1 solution)
(B)25-4x = 15-3x+10-x
25-4x = 5-4x
25-5 = 4x-4x
30 = 0 (No solution)
(C)4x+8 = 2x+7+2x-20
4x+8 = 4x -13
4x-4x = -13-8
0 = -21 (No solution)
Answer: D and E I'm sure
