Answer: x=7
Step-by-step explanation:
8 + 4 = 2(x - 1) combine like terms on the left side
12 = 2(x -1) Distribute on the right side
12 = 2x - 2 Add 2 to both sides
+2 +2
14 = 2x Divide both sides by 2
x= 7
A (-4,5)
B (-3,1)
C (-5,2)
A'(3,1)
B'(2,5)
C'(4,4)
6 non zero multiple of 12 are 24,36,48,72,84,96.
