Paul [167]

Answer:

D or 3

Step-by-step explanation:

The equation you are saying is

-x = x-6

If you move both x's to one side, you get

-2x = -6

From this, you can simplify by dividing by -2

x=3, or D.

Hope this helped!

The solution of the system is (400, 3,200). How would you interpret this solution?

alekssr [168]

The solution (400, 3, 200) is the answer to a system of equations which has three variables. Respectively, this system is expected to have three equations because it has three unknowns. So for example if your unknowns are x, y and z, then the answers will be x=400, y=3, and z=200.

2 x + 3 y = 11 x − 3 y = 1 What is the solution ( x , y ) to the given system of equations?

Nitella [24]

Answer:

(4, 1 )

Step-by-step explanation:

Given the 2 equations

2x + 3y = 11 → (1)

x - 3y = 1 → (2)

Adding (1) and (2) term by term will eliminate the term in y

3x = 12 ( divide both sides by 3 )

x = 4

Substitute x = 4 into either of the 2 equations and evaluate for y

Substituting into (1)

2(4) + 3y = 11

8 + 3y = 11 ( subtract 8 from both sides )

3y = 3 ( divide both sides by 3 )

y = 1

Solution is (4, 1 )
