WebTake the two equations that contain z and solve for z. 3x+5y-4z=36 4z = 3x+5y- 36 z = ¼ [3x+5y- 36] 12x+2y+3z=19 3z = −12x − 2y + 19 z = ⅓ [−12x − 2y + 19] Since we now have to things that are equal to z, we set them equal to each other, eliminating the z. ¼ [3x+5y- 36] = ⅓ [−12x − 2y + 19] WebAlgebra. Divide x/ (y/z) x y z x y z. Multiply the numerator by the reciprocal of the denominator.

WebDescription. X = linsolve (A,B) solves the matrix equation AX = B, where B is a column vector. [X,R] = linsolve (A,B) also returns the reciprocal of the condition number of A if A is a square matrix. Otherwise, linsolve returns the rank of A.
