Instructions:
Solve a set of two equations with two unknowns and find out values of unknown variables x and y.
Example
2 . x - 1 . y | = | -2 |
-1 . x + 1 . y | = | -1 |
= | ||
= | ||
= | ||
x | = | |
y | = | |
Correctness test | ||
2 . - 1 . | = | -2 |
-1 . + 1 . | = | -1 |
Solution
2 . x - 1 . y | = | -2 |
-1 . x + 1 . y | = | -1 |
x | = | -3 |
y | = | -4 |
