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

x = 3

y = 2

Step-by-step explanation:

x - 3y = -3

x + 3y = 9

Solve for x in the second equation.

x = 9 - 3y

Pu x as 9 - 3y in the first equation and solve for y.

9 - 3y - 3y = -3

9 - 6y = -3

-6y = -12

y = 2

Put y as 2 in the second equation and solve for x.

x = 9 - 3(2)

x = 9 - 6

x = 3
