Solve the system of equations x-y = 2 2x-3y = -1

We express x from the first equation and substitute it into the second:
X = 2 + y;
2 (2 + y) – 3y = – 1;
Let’s expand the brackets
4 + 2y – 3y = – 1;
We present similar terms and transfer 4 to the other side, while changing the sign to the opposite:
– y = – 1 – 4;
– y = – 5;
Now let’s find x:
X = 2 + 5 = 7.
Answer: x = 74 y = 5.
