25 5 10 2 5 2. For example if Px y and Qx y are two polynomials in the variables x and y and if a b c and d are real or complex numbers then the two systems Px y 0 Qx y 0 and a Px y bQx y 0 cPx y dQx y 0 are equivalent when the value of the determinant ad bc 0. Write an equivalent equation you can use to solve each equation.
The same is true for y values.
A b is equivalent to a - c b - c Multiplication Property of Equality states that when we multiply the same quantity to both sides of an equation the equation remains true. Video ExamplesSolving Linear Equations. Are the equations x 7 and x 2 9 equivalent. An Equation is a mathematical sentence that uses the equal sign to show that two expressions are equal.
