Solve {l}{a_{2}=48}{a_{4}=75}{a=a_{1}}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { a_{2} = 48 }\\ { a_{4} = 75 }\\ { a = a_{1} }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Solve for a_2, a_4, a, a_1, b

$$a_{2}=48$$

$$a_{4}=75$$

$$a=b$$

$$a_{1}=b$$
