Answer:

(3, 0)

Step-by-step explanation:

we have

[tex]7x+3y=21[/tex]

we know that

The x-intercept is the value of x when the value of y is equal to zero

so

For y=0

substitute in the equation and solve for x

[tex]7x+3(0)=21[/tex]

[tex]7x=21[/tex]

Divide by 7 both sides

[tex]x=3[/tex]

therefore

The x-intercept is the point (3,0)
