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)

Using the method of substitution solve the problem need help completely loss if you can do it quickly it would help

miv72 [106K]

Equation 1) y=x+3
Equation 2) y=2x+5

Rearrange both equations so that (x) and (y) are on the same side.

1) -x+y=3
2) -2x+y=5

Subtract equations with each other.

x=-2

Plug in -2 for (x) in equation 1.

y=(-2)+3

Simplify.

y=1

(-2, 1)

~Hope I helped!~
