$x=3\\y=2$

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:

$2x+3y=12\\2x+3(x-1)=12\\2x+3x-3=12\\5x=12+3\\5x=15\\x=3$

- Substitute the value of x obtained above into the second equation to find the value of the variable y. Therefore, you obtain:

$y=x-1\\y=3-1\\y=2$
