Here are the solutions: 38. y=5y=-5; 39. t=2.7t=2.7; 40. x=63.67x=63.67; 41. c=5c=5; 42. x=10.5x=-10.5; 43. d=3.8d=-3.8; 44. d=613d=-6 \frac{1}{3}; 45. m=0.449m=0.449; 46. t=70t=-70; 47. p=2p=-2; 48. k=4k=4; 49. c=70c=70; 50.
There seems to be a typo in the problem, as the variable z is not present in the equation.
Assuming it was meant to be solved for z, then the solution would be any value of z, as it simplifies to 11=2, which is false.
