Answer:
1. x = 2
2. x = 4
Step-by-step explanation:
1. 6 - 4x = 6x -8x + 2
6 - 4x = -2x + 2
+4x +4x
6 = 2x + 2
-2 -2
4 = 2x
/2 /2
2 = x
2.
6 - 6x = 5x -9x -2
6 - 6x = -4x -2
+6x +6x
6 = 2x -2
+2 +2
8 = 2x
4 = x
C) 9
54 = 2 x 3 x 3 x 3
81 = 3 x 3 x 3 x 3
common factor of 54 and 81 = 3 x 3 = 9
Answer: 9
