$${\mathtt{14}}{\mathtt{\,\times\,}}{\mathtt{a}}{\mathtt{\,-\,}}{\mathtt{93}} = {\mathtt{49}}{\mathtt{\,-\,}}{\mathtt{57}}{\mathtt{\,\times\,}}{\mathtt{a}} \Rightarrow {\mathtt{a}} = {\mathtt{2}}$$
+427 14a - 93 = 49 - 57a
First let's re-arrange the equation so all "a"s are on one side.
14a + 57a - 93 = 49
14a + 57a = 49 + 93
Simplifying it down
71a = 142
Divide both sides by 71 so it's just "a" as the subject.
a = 142 / 71
a = 2
