<PRE><B>Question 29595</B>
-s+4=7s-3  
4+3 = 7s+s  (grouping like terms, changing sign while changing side)
(same as adding 3 to both the sides and adding s to both the sides)
7=8s
That is 8s = 7
Therefore s = 7/8 (dividing by 8)
Verification: putting s = 7/t,
Lhs = -s+4 = (-7/8)+4 =(-7+32)/8= 25/8
RHS = 7s-3 = 7X(7/8)-3 = (49-24)/8 = 25/8 =LHS
Therefore our value for s is correct</PRE>
