3x - 3y = 9 and x + 3y = 12 <br> Elimination
Firlakuza [10]

Answer:

x=5.25,y=2.25

Step-by-step explanation:

We can add the two equations to eliminate the variable y and solve for x:

3x-3y+x+3y=9+12

4x=21

x=5.25

Now, we can use substitution to solve for y:

x+3y=12 (given)

5.25+3y=12

3y=12-5.25

=6.75

y=2.25

Hope this helps :)
