Homework Statement


So, I know how to solve multiple equations using the cSolve method on the ti 89, but for some reason when I try to solve the following...

80a + 240b = 0 and (80+J79.975)a-80b = 50 by using the following syntax...


cSolve(80a + 240b = 0 and (80+J79.975)a-80b = 50 ,{a,b})

I get a message saying that there are too many arguements, what am I doing wrong?

When all else fails, try reading the instructions.

The proper complex number has a format of a + b*i, not a + b*J

I know that haha, as it turns out, in my calculator for some reason you cannot use a and b as algebraic variables, it works perfectly fine using any other variable XD
