Best Answer

In Roman numerals L and C are 50 and 100 respectively. So substitute 50 and 100 into the equation and let the unknown be called z. 50-z = 100 -z = 100-50 -z = 50 --z = -50 Solution: z = -50 Substituting -50 into the equation: 50--50 = 100 or L--L = C. Remember that in maths a double minus sign before a number changes that number into a plus number. Check it out on your calculator. David Gambell, Merseyside, England.

Which equation has the same unknown value as 430 5?

"430 5" is not an equation and it does not have an unknown value. So there can be no equation which has the same unknown value.


How do you solve a equation using unknown variables?

You don't use unknown variables to solve an equation. The purpose of solving an equation is to find the value of the variable so that it's no longer unknown.


What is the term used for a quantity which when substituted for the unknown quantity in an equation satisfies the equation?

It is the solution to the equation or a root of the equation.


When does the nonlinear equation becomes linear equation?

A linear equation is defined as an equation that contains only the first power of the unknown quantity. For example, 5x - 3 = 7 where "x" is the unknown quantity is a linear equation. If an equation contains an unknown quantity having a higher power than 1, then the equation ceases to be a linear equation. For example, 3x2 + 5x + 7 = 0 is a non linear equation known as a quadratic equation, because the unknown quantity "x" has a power of 2. Similarly, equations containing unknowns with higher powers such as x3, x7, x12 are all non linear equations.


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 algebra ygb-iboe-hvz?

Algebra ygb-iboe-hvz is a type of algebraic equation known as a "ygb-iboe-hvz equation". This type of equation is a type of linear equation that is commonly used to solve for the unknown variable in a given equation. The equation is composed of three terms: ygb, iboe, and hvz. The ygb term is the coefficient of the unknown variable, the iboe term is the constant, and the hvz term is the right-hand side of the equation. To solve the equation, the coefficients of each term must be determined and the equation must be rearranged to solve for the unknown variable.
