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)

The answer is C: (3,3)

x+3y=12;−4x+3y=−3Step: Solvex+3y=12for x:x+3y+−3y=12+−3y(Add -3y to both sides)x=−3y+12Step: Substitute−3y+12forxin−4x+3y=−3:−4x+3y=−3−4(−3y+12)+3y=−315y−48=−3(Simplify both sides of the equation)15y−48+48=−3+48(Add 48 to both sides)15y=45‌15y15‌=‌4515‌(Divide both sides by 15)y=3Step: Substitute3foryinx=−3y+12:x=−3y+12x=(−3)(3)+12x=3(Simplify both sides of the equation)

Hope this helps!

2. root 6 is the right answer

Using the rise/run rule. you would get 2/6.simp. 1/3
