Plug in the given values for either x or y and solve for the other.

When x = 7 , y = ?

Plug in 7 for x in the given equation:

y = x - 3

y = 7 - 3

y = 4

When x = 7, y = 4

When x = ? , y = 1

Plug in 1 for y in the given equation:

1 = x - 3

1 (+3) = x - 3 (+3)

x = 1 + 3

x = 4

When x = 4, y = 1

When x = ? , y = 7

Plug in 7 for y in the given equation:

7 = x - 3

7 (+3) = x - 3 (+3)

x = 7 + 3

x = 10

When x = 10, y = 7

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)
