12 -9 + x = 3 -9 + x + 9 = 3 + 9 x = 3 + 9 x = 12
3 x 3 x 3
X + 3 = 9 x + 3 - 3 = 9 - 3 x = 6
9 x 9 x 3 = 81 x 3 = 243
9 + x = 3 x = 3-9 x = -6 Check 9 + (-6) = 3 9 - 6 = 3

9 + x = 3 x = 3-9 x = -6 Check 9 + (-6) = 3 9 - 6 = 3
x**2-9-9 factors into 3,-33+-3=0x**2-9=(x-3)(x+3)3x-9=3(x-3)(x-3)=LCM
1, 3, 9 3 x 3 = 9 1 x 9 = 9 9 x 1 = 9
9 = 1 x 9, 3 x 3, 9 x 1
factors of 9 are 1, 3 and 9
If x/3 = 9, then x = 27.
