What is the solution to the system of equations below?

Karolina [17]

Answer:

The solution is the point (18,0)

Step-by-step explanation:

we have

$y=-\frac{1}{3}x+6$ -----> equation A

$y=\frac{1}{3}x-6$ -----> equation B

Solve the system by substitution

substitute equation B in equation A

$\frac{1}{3}x-6=-\frac{1}{3}x+6$

solve for x

Adds (1/3)x both sides

$\frac{1}{3}x-6+\frac{1}{3}x=6$

$\frac{2}{3}x-6=6$

Adds 6 both sides

$\frac{2}{3}x=6+6$

$\frac{2}{3}x=12$

$x=12(3)/2\\x=18$

<em>Find the value of y</em>

substitute the value of x in equation A or equation B

$y=-\frac{1}{3}(18)+6=0$

therefore

The solution is the point (18,0)

Compare the values of the two 8s in the number 467,882

Ludmilka [50]

The 8 in position 4 (from the left) means 800 and the 5th 8 means 80

so position 4 8 is ten times the the next 8. - as you would expect because its the decimal system based on 10.

difference = 800-80 = 720.
