PLEASE HELP EASY!! Which ordered pair is the solution to the system of equations?

{y=3x−12
4x+6y=−6

(6, −5)

(0, −12)

(3, −3)

(4, −7)

Step-by-step explanation:

Put the coordinates of the given points to the equations and check the equality.

for (6, -5)

(1)

-5 = 3(6) - 12

-5 = 18 - 12

-5 = 6   FALSE

for (0, -12)

(1)

-12 = 3(0) - 12

-12 = 0 - 12

-12 = -12    TRUE

(2)

4(0) + 6(-12) = -6

0 - 72 = -6

-72 = -6    FALSE

for (3, -3)

(1)

-3 = 3(3) - 12

-3 = 9 - 12

-3 = -3    TRUE

(2)

4(3) + 6(-3) = -6

12 - 18 = -6

-6 = -6    TRUE

for (4, -7)

(1)

-7 = 3(4) - 12

-7 = 12 - 12

-7 = 0    FALSE

ANSWER: (3, -3)

Solve the system of equations:

substitute (1) to (2):

put it to (1):

28

step-by-step explanation:

because that's the answer

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
