WebMay 25, 2024 · This involves fluid flowing through a pipe and then branching off into parallel branches that recombine downstream. This is similiar to solving an electrical circuit via nodal and loop analysis, however the equations are inherently non-linear, and must be solved iterratively and not simply with inv(). free hosting for java web application

Literal Equations and Equations... Step-by-Step Math Problem Solver

WebTake the solution (s) and put them in the original equation to see if they really work. Example: solve for x: 2x x − 3 + 3 = 6 x − 3 (x≠3) We have said x≠3 to avoid a division by zero. Let's multiply through by (x − 3): 2x + 3 (x−3) = 6 Bring the 6 to the left: 2x + 3 (x−3) − 6 = 0 Expand and solve: 2x + 3x − 9 − 6 = 0 5x − 15 = 0 5 (x − 3) = 0 WebMar 27, 2024 · This type of three-step linear equation must be simplified in order for it to be solved.
