\( \begin{array}{ll}\text { a. } & x+7=0 \\ \text { c. } & 2 x-7=3 \\ \text { e. } & 5 x-8=2 x-2 \\ \text { g. } & 7(y-2)+21=(2 y)(3)\end{array} \)

To solve these equations, it’s helpful to get to know some clever strategies! For example, isolating the variable is a solid first step. In equation **a**, subtract 7 from both sides to find \(x\). In equation **c**, start by adding 7, then divide by 2 to unravel \(x\). Also, keep an eye out for common mistakes! When dealing with distributive properties like in equation **g**, be meticulous about distributing to every term inside the parentheses. Don’t forget to combine like terms efficiently in equations **e** and **g**; it's easy to overlook or mishandle them under pressure!
