Need answer step by step

(-6, 2)

Step-by-step explanation:

Multiply the second equation by 2

2x - 6y = -24

then add both equations together.

4x + 6y = -12

6x          = -36, divide both sides by 6

x = -6

then plug -6 back into either equation and solve for y

-6 - 3y = -12

-3y = -6

y = 2

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
