How to solve the system of equation 500y-600x=2800 , 400y-400x=2400 by elimination
tatiyna

Answer:

x=2 and y=8

Step-by-step explanation:

Given:

Equation 1:

500y-600x=2800

Simplifying the above equation by dividing both sides by 100

\frac{500y-600x}{100}=\frac{2800}{100}

\frac{500y}{100}-\frac{600x}{100}=28\\\\5y-6x=28

Equation 2:

400y-400x=2400

Simplifying the above equation by dividing both sides by 400.

\frac{400y-400x}{400}=\frac{2400}{400}

\frac{400y}{400}-\frac{400x}{400}=6\\\\y-x=6

Now the system of equation is:

(1a) 5y-6x=28

(2a) y-x=6

Solving by elimination

Multiplying equation (2a) with -5

-5(y-x)=-5\times 6

(2b) -5y+5x=-30

Adding equations (1a) and (2b) in order to eliminate y

      5y-6x=28

+  -5y+5x=-30

We get -x=-2

∴ x=2

Plugging x=2 in equation (2a).

y-2=6

Adding 2 both sides.

y-2+2=6+2

∴ y=8

Find the value of x so that the function has the given value. 2(x) = 2x + 7; n(x) = 17​
Galina-37 [17]

Answer:

  x = 5

Step-by-step explanation:

Maybe you have ...

  n(x) = 2x +7

and you want x for n(x) = 17.

  17 = 2x +7

  10 = 2x . . . . . . subtract 7

  5 = x . . . . . . . . divide by 2
