Y=-3x+9
y=-x-5

what is the solution for the system of equations?

Our system of equations is:

y = -3x + 9

y = -x - 5

To solve this system of equations, we are going to use substitution. This means that we are going to substitute the second equation into the first equation since both are already solved for y in terms of x.

y = -3x + 9

-x - 5 = -3x + 9

Now, we must simplify by moving all of the constant terms to one side of the equation and all of the variable terms to the other side.

-x - 5 = -3x + 9

2x - 5 = 9

2x = 14

Finally, to undo the multiplication between the coefficient 2 and the variable x, we must divide both sides by 2 to get the variable x alone.

x = 7

Next, we must substitute in this value we have solved for x into one of the original equations to solve for the other variable, y.

y = -3x + 9

y = -3(7) + 9

To simplify, we must multiply through the parentheses and combine like terms by addition.

y = -21 + 9

y = -12

Therefore, your final answer is x = 7 and y = -12, or as an ordered pair (7, -12).

Hope this helps!

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.

step-by-step explanation: 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.
