Can someone explain how they got the answer to this?

you need to solve for x.

5x+10=20

    -10 -10

5x=10

/5   /5

x=2

Step-by-step explanation:

let me know if this wasn't what you were asking for.

x=2

Step-by-step explanation:

5x + 10 = 20

    - 10     -10

5x = 10

5x/5 = 10/5

x = 2

hope this helped :)

answer: true

step-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
