Solve the system of linear equations x - 3y = - 3 x + 3y = 9

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

collect like terms

-3x will go to x and it will turn to

x+3x And - 3y will go to + 3y and it will turn to

*+3x=+3y+3y=9

solving time.

x+3x is 4x

3y + 3y = 6y

4x+6y = 9

remove the 4x for now.

6y divided by 9.

3 in 6 is 2 and 3 in 9 is 3.

therefore 4x = 2=9

4/2=2

2x=9.

4and half is the answer
