"one quarter of a number increased by 5" is an expression. It is NOT an equation. There is, therefore, no method that can be used to determine what the number is.
The first number you use in an iterative equation/method is known as the initial point and is often symbolised with a subscript 0 like so, x0.
Methods vary considerably depending upon the number of powers in the equation. For example, the method for solving cubics is quite different to solving quadratics etc... It's not really possible to generalise to one technique.
The answer depends on the equation: there is no single method which can be used for all equations.
Standard equation for a circle centred at the origin is x2 + y2 = r2 where r is the radius of the circle. If you increase the size of the circle then the radius must increase, so r2 will be larger. eg a circle of radius 2 has the equation x2 + y2 = 4, if the radius increases to 3 then the equation becomes x2 + y2 = 9
Since a percentage is just a way to express a number as a portion of 100, set up an equation. The percentage over 100 needs to equal the increase over the original number.Let's say the price of gas increased from $2 to $3. The increase is 3 - 2 = 1. Put the increase over the original number and let x=the percentage:1/2 = x/100Multiply both sides of the equation by 100 to get xalone.100/2 = x100/2 = 50 = x, so the price of gas increased by 50%.
Let's set this equation up. Call the original number No and the number you have N and the percentage increase P. The equation to get the number you have ( N ) is No + No x P = N and we want to solve for No so No ( 1 + P ) = N No = N / ( 1 + P )

x2 + y2 = r2, the equation of a circle centered at the origin. If you want to make the circle larger, increase the radius length.

Telemarketing is used by a number of companies as a direct marketing method. It allows you to target prospective customers, increase your sales, and increase the visibility of your company.
Mn increase in oxidation number from +4 to +7.
Substitute the number in the equation. If the resulting statement is true the number is a solution to the equation.
