For example, the simultaneous equations \(3a + 2b = 17\) and \(4a - b = 30\) have no common coefficient as the coefficients of \(a\) are 3 and 4, and the coefficients of \(b\) are 2 and -1. Remember ...
'I think of a number, add four, and the answer is seven.' Written algebraically, this statement is \(x + 4 = 7\), where \(x\) represents the number you thought of. \(x + 4 = 7\) is an example of an ...
