Worksheet 2 2 Solving Equations in One Variable

70 = T +2 7 (multiply out the brackets) 70 = T +14 70 14 = T +14 14 56 = T Note: When multiplying through by a number it is important to multiply every term on both sides of the equation. On the whole, it is probably easier to undo addition and subtraction rst. Example 2 : 3x 5 = 16 3x 5+5 = 16+5 (add 5 to both sides) 3x = 21 3x 3 = 21 3 x = 7 ...

Section 2 Properties of Logs Logs have some very useful properties which follow from their de nition and the equivalence of the logarithmic form and exponential form. Some useful properties are as follows: logb mn = logb m+logb n logb m n = logb m logb n logb m a = alog b m logb m = logb n if and only if m = n Page 2
