"WebMar 20, 2016 · so z = ± 3. The first equation gives a = ± 3 and the second b = 0. After substitution you can solve the first square to obtain: in other words: 2 a 2 + 2 a b i = 18. Now 18 is real, this mean: a = 0 or b = 0. If a = 0 then 0 = 18 which is false, so b = 0; then 2 a 2 = 18, so the solutions are a = ± 3. Correct. " - Two unknown calculator

WebThe answer to the original question 'Is it possible to solve for two variables related by single equation' is, YES! Here is an example. Solve for two unknown real numbers x and y given a single equation. x + y − 1 = 1 − y 4. The only real solutions are x = 0, y = 1. Solution As x, y are real numbers, either y − 1 ≥ 0 or 1 − y ≤ 0. WebWith its ability to algebra, the calculator can solve equations with two unknown or solve equations with 3 unknowns involving letters (literal calculation).

To find the linear equation you need to know the slope and the y-intercept of the line. To find the slope use the formula m = (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are two points on the line. The y-intercept is the point at which x=0.
