4c2 + 5c + 2c = 4c2 + 7c = c(4c + 7)
24c3 + 375z3 = 3*(8c3 + 125z3) = 3*(2c + 5z)*(4c2 - 10cz + 25z2)
24c2 + 96c + 90 = 6*(4c2 + 16c + 15) = 6*(2c + 3)*(2c + 5)
Let c represent cos x. Then, we have, 4c2 - 2 = 0; whence, 4c2 = 2, c2 = ½, and c = ±√½ = ±½√2; that is, cos x = ±½√2. From this, it is evident that, for 0 ≤ x < 360°, x = 45°, 135°, 225°, or 315°; or, if you prefer, for 0 ≤ x < 2π, x = ¼π, ¾π, 1¼π, or 1¾ π.

Not enough information to solve
If: a = b+c+d Then: c = a-b-d
You cannot solve x plus y since that is an expression, not an equation (nor inequality).
Simplified its 12r+3s
There's nothing to solve, it's simply an expression.
