3Y - 2 = X + 5 This presumes "a number" and "x" are two separate values. If they are the same number, the equation would be 3X - 2 = X + 5. In this equation, X = 3.5.
Call your number "x", write an equation, and solve it: 8x = x + 49 7x = 49 x = 7

Expressed as an equation, this would be equal to 13x - 3.
48-n=4n-7
X = number 48 - X = 4X - 7

To solve this you'll need to write an equation, since you don't know enough information to find an answer. Start with the multiplication part of the equation, which is "the product of a number and 4." This is written as 4x. Then you just need to subtract the 18, giving you 4x-18. Now you can substitute any number in for x and solve to get an answer.
(N/5) x (2) = 1Divide each side of the equation by 2:(N/5) = 0.5Multiply each side by 5 :N = 2.5
