which ordered pair is the solution to the system of equations?
x+3y=12
-4x+3y=-3
a.
(0, 4)
b.
(6, 2)
c.
(3, 3)
d.
(0, −1)

solve x+3y=12 for x

Add -3y to both sides

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

x= -3y+12

Substitute -3y+12 for x in -4x+3y= -3

-4x+3y = -3

-4(-3y+12)= + 3y = -3

Simplify both sides of the equation

15y-48= -3

Add 48 to both sides

15y-48+48= -3+48

15y = 45

Divide both sides by 15

15y/15 = 45/15

y= 3

Substitute 3 for y in x = -3y+12

x = -3y+12

x= (-3)(3)+12

 Simplify both sides of the equation

x= 3

Answer : x= 3 and y= 3

                (3,3)

                C is the answer

I hope that's help !
