Knowing that, the OP should be able to easily fix A1 and A3.

I agree. This particular system lends itself to using Cramer's rule because of all the zeroes on the right hand side.Knowing that, the OP should be able to easily fix A1 and A3.

These two equations are shown in the system:The systemislinear in A_{1}, A_{2}, A_{3}, and A_{4}.

Not linear. That shows an exponent of 2 on the w. If I misunderstand, then w is not a variable; but A1, A2, and A3 must be the variables. If this latter is the case, then yes; linear system.dA1 + cA2 + w^2 A3 = 1

dA2 + w^2A4 = 0
