Linear equation
In mathematics, a linear equation is an equation that may be put in the form + ⋯ + + =, where , …, are the variables (or unknowns), and ,, …, are the coefficients, which are often real numbers.The coefficients may be considered as parameters of the equation, and may be arbitrary expressions, provided they do not contain any of the variables.

 · PDF 檔案Note that in an equation of the form y = 5+3×2, taking logs directly does not help. This is because there is no rule to simplify log(5+3×2). Instead we have to subtract the constant from each side.We then get: y − 5 = 3×2, which leads to the straight line equation

方程式求解問題
事實上,方程式 2x 5 +5=0 有根式解,但是 2x 5-10x+5=0 沒有根式解。法國數學家 Galois 在1832年提出任意(數字或文字)方程式有根式解的充分必要條件。Galois 把方程式求解問題轉化成置換群 (permutation group) 的問題。他在繁複的計算中洞見方程式求解

Working with Exponents and Logarithms

So a logarithm actually gives you the exponent as its answer: (Also see how Exponents, Roots and Logarithms are related.) Working Together Exponents and Logarithms work well together because they “undo” each other (so long as the base “a” is the same):
