<PRE><B>Question 759038</B>
Determine the value of the unknown 
1.1 X-3 over4-x+2 over 3=3
(x-3)/4 - (x+2)/3 = 3
------
3(x-3) - 4(x+2) = 36
3x-9-4x-8 = 36
-x - 17 = 36
-x = 53
x = -53
----------------

1.2 (a-1)(a+1)=0 
a = 1 or a = -1
-------------------
1.3 2 over 3a+7=3
2/(3a+7) = 3
2 = 9a+21
9a = -19
a = -19/9
------------------- 
1.4 name four conditions for congruency
Congruency of what??
