Answer:
Step-by-step explanation:
You con solve the system of equation with the Substitution method, as following:
- Substitute the second equation into the first equation.
- Solve for x:
- Substitute the value of x obtained above into the second equation to find the value of the variable y. Therefore, you obtain:
X=3
Y=2
2x+3y=12
2*3=6
3*2=6
2*3+3*2=12
6+6=12
2-3=-1
