Solve the system using substitution and describe your steps

x = y - 3
2x + y = 12

Step-by-step explanation:

We have already defined that x = y - 3, replace x for this value.

Distribute 2.

Add 6.

Combine like terms;

Divide by 3.

After having found a variable value, in this case y, replace it in the other equation; x = y - 3, to find x.

x=6 and x=3
