If 101\(_{\text{two}}\) + 12y = 3.3\(_{\text{five}}\). Find the value of y

An amount of N550,000.00 was realized when a principal, x was saved at 2% simple interest for 5 years. Find the value of x

Given that \(\frac{\sqrt{3} + \sqrt{5}}{\sqrt{5}}\) 

= x + y\(\sqrt{15}\), find the value of (x + y) 

If x = 3 and y = -1, evaluate 2(x\(^2\) - y\(^2\))

Solve 3x - 2y = 10 and x + 3y = 7 simultaneously
