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.
x-intercept = 4
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)
