This 3 equations 3 unknown variables solver computes the output value of the variables X and Y with respect to the input values of X, Y and Z coefficients In mathematic calculations, there are many situation arises where the usage of equation containing 3 unknown variables need to be solved prior to go further with the calculationsGet stepbystep solutions from expert tutors as fast as 1530 minutesReflections A reflection is a transformation representing a flip of a figure Figures may be reflected in a point, a line, or a plane When reflecting a figure in a line or in a point, the image is congruent to the preimage A reflection maps every point of a figure to an image across a fixed line The fixed line is called the line of reflection
If b ≠ 0, the equation = is a linear equation in the single variable y for every value of xIt has therefore a unique solution for y, which is given by = This defines a functionThe graph of this function is a line with slope and yintercept The functions whose graph is a line are generally called linear functions in the context of calculusHowever, in linear algebra, a linear functionSolve for x and y Equation A y x = 3 Equation B x = y 5 y x = 3 x = y 5 The goal of the substitution method is to rewrite one of the equations in terms of a single variable Equation B tells us that x = y 5, so it makes sense to substitute that y 5 into Equation A for x y x = 3 y (y 5) = 3 Substitute y 5 intoShow, by left side, that $$\frac{x^3y^3}{xy} = x^2xyy^2,$$ or $$\frac{x^3y^3}{x^2xyy^2} = xy$$ You may read about "Long Division of Polynomials" See also LINK for knowing the process
