If you have a function, such as y=2x also written as f(x)=2x, then you plug in the number. So for example if x=1 then you have y=2
or f(1)=2.

If you want to find x percent of a number y then you need to calculate y*(x/100). It makes no difference whether y is a whole number or not.
If the mixed number is x y/z then the numerator is (x*z + y)
Because this question has more than one variable( x and y) the solution is impossible to find (a number). To make it easier to find x or y, x = a - y + 3 y = 3 - x - a where a = y - x + 3
x=number 1, y=number 2 {x-y=20} {x+y=48} x=y+20 y+20+y=48 2y=28 [y=14] x=14+20 [x=34]
To find the number that, when subtracted from another number, equals 46, you can set up the equation: ( x - y = 46 ), where ( x ) is the number you are subtracting from, and ( y ) is the number being subtracted. For example, if ( y = 0 ), then ( x ) would be 46. The specific values of ( x ) and ( y ) can vary, but the difference will always be 46.
