.
Two variables are involved in this set of two equations ... x and y. But the problem
already tells you that x is equal to -1. With this information you can solve for y by
substitution. Just substitute -1 for x in the top equation. When you do the top equation
becomes:
.

.
This simplifies to:
.

.
Eliminate the -2 on the left side by adding +2 to both sides to get:
.

.
Solve for y by dividing both sides by 3. This results in:
.

.
The decimal equivalent of this is:
.

.
Hope this helps you to understand a way of solving the equation.
