The answer is: Substitution property of equality.
The explanation is shown below:
1. To solve this problem you must apply the proccedure shown below:
2. When you clear the variable x from the first equation, and subtitute it into the second equation, you obtain:
3x−2y=10
x=(10+2y)/3
4x−3y=14
4[(10+2y)/]−3y=14
y=-2
3. When you subsitute y=-2 into the first equation and clear the x, you have:
x=2
