Solve the formula for the indicated variable.{eq}\displaystyle{ \rm P = a + 3b + 2c,\ for\ a } {/eq}
Here, the given expression is {eq}P = a + 3b + 2c {/eq}. We have to find the value {eq}a. {/eq}
{eq}\begin{align} \therefore P & = a + 3b + 2c \\[0.3 cm] a & = P - 3b - 2c \\[0.3 cm] \end{align} {/eq}
Therefore, {eq}\boxed{a = P - 3b - 2c}. {/eq}
