How can you find a variable in math?
You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables. Then you solve the equation(s), using algebra.You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables.

What is seven times a number in algebraic terms?
It is simply: 7y whereas y is the unknown variable
What is the best method for solving a set of two linear equations?
If this involves two equations both containing the same two unknowns, then multiply (or divide) one of the equations so that the absolute value of one of the unknowns is now the same in both equations. For example, x + 2y = 11 : 3x - 57 = 13 : Multiply the first equation by three, 3x + 6y = 33 so that the 'x' terms in this and the second equations are equal. In this example they both have the same (positive) sign - see below.If this unknown has identical signs (both are positive or both are negative) then subtract one equation from the other to eliminate that unknown.If this unknown has different signs (it is positive in one equation and negative in the other equation) then add the equations together to eliminate that unknown.This will enable the value of the remaining unknown to be determined and by substitution the value of the eliminated unknown can then be found.
What are the classifications of algebraic expression?
1 term = Monomial2 term = Binomial3 term = trinomialNo standard for 4, or any larger fixed number of terms, but "polynomial" is used when the number of terms is unknown.
Why are conjectures important in finding unknown terms in a sequence or pattern of numbers?
In order to find the unknown term in a number sequence, you first need to calaculate the advantage of the numbers.
