Question

The equation 13x + 1 = 5 – x can be solved by graphing y = 13x + 1 and y = 5 – x.

Answer 1

Answer:

The graph shows that when x =3 both

$\frac{1}{3}x + 1$

and 5 – x equal 2

Step-by-step explanation:

The equation 13x + 1 = 5 – x can be solved by graphing y = 13x + 1 and y = 5 – x.

From the graph, the two lines representing the two equations intersect at (3,2).

This implies that the solution to the system

$y = \frac{1}{3} x + 1$

and

y=5-x

is x=3, y=2

Hence the value of the two functions equals 2 at x=3.
