1. Solve the following equation for n: n/4-5/6 = 5/12 2. Solve the following equation for x: 2x/3 -4x/5 =1/15 3. Solve the following equation for x: 9(4x)+1/3=5(2x) 4. Subtract the complex numbers: (4+3i)-(6+I) 5. Multiple the complex numbers (4+3i)(6+I) Need step by step example on how these are done. Thank you
