Answer:

(4,0) or 4

Explanation:

The x intercept is calculated by plugging the y value of zero in for y. Doing this will get you 5x=20. Lastly, divide both sides by 5 to get 4.

Answer:

x-intercept = 4

Explanation:

when x-intercept, y shall be 0; when y-intercept, x shall be 0

5x + 2y = 20

[ consider y as 0 ]

5x + 2(0) = 20

[ simplify ]

5x = 20

[ divide both sides by 5 ]

x = 4

coordinate of x-intercept at (4,0)
