Answer:

10

Step-by-step explanation:

x- intercept is where the equation intersect the x-axis. So, at x-axis y = 0

2x + 4*0 = 20

           2x = 20

Divide both sides by 2

2x /2 = 20/2

x = 10

Answer:

[tex]x = 10[/tex]

Step-by-step explanation:

To find x-intercept/zero, substitute y = 0.

[tex]2x + 4 \times 0 = 20[/tex]

Any expression multiplied by 0 equals 0.

[tex]2x + 0 = 20[/tex]

When adding or subtracting 0, the quantify does not change.

[tex]2x = 20[/tex]

Divide both side of the equation by 2:

[tex]x = 10[/tex]
