Question

What is the solution to the system of equations below?

Answer 1

Answer:

(18,0)

Step-by-step explanation:

Answer 2

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

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

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

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

Find the value of y

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)
