Instructions:
Solve a set of two equations with two unknowns and find out values of unknown variables x and y.
Example
1 . x - 1 . y | = | -2 |
-2 . x - 1 . y | = | 1 |
= | ||
= | ||
= | ||
x | = | |
y | = | |
Correctness test | ||
1 . - 1 . | = | -2 |
-2 . - 1 . | = | 1 |
Solution
1 . x - 1 . y | = | -2 |
-2 . x - 1 . y | = | 1 |
x | = | -1 |
y | = | 1 |
