this can not be solved un less with another equation

if n is your number, then 3n - 5 = 16, ie 3n = 21 ie n = 7.

You do the following: 1) Solve one of the equations for one of the variables 2) Substitute this variable in the other equation or equations 3) Simplify This should normally give you one less equation than the original set, with one less variables. For example:

As an equation, x = -2y cannot be solved without further information. To solve an equation (or multiple equations), the number of unknowns (x, y etc.) must be equal to or less than the number of equations. In your example you have 2 unknowns and 1 equation, so it does not work.

SRY THE Q IS HOW CAN YOU WRITE AND SOLVE: Twenty four is three less than one-third of a number.?

You can write an equivalent equation from a selected equation in the system of equations to isolate a variable. You can then take that variable and substitute it into the other equations. Then you will have a system of equations with one less equation and one less variable and it will be simpler to solve.

I guess you mean an equation written in function notation, for example: f(x) = 3x + 2 For the purposes of doing math, it may help to think of this as an alternative way of writing, for example (using the function above): y = 3x + 2 It isn't clear from the question what you want to "solve", but if you write the equation this way, it might become a bit less confusing.

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.
