Answer:

[tex]x=15[/tex]

Step-by-step explanation:

we have

[tex]\frac{5}{7}=\frac{x}{21}[/tex]

solve for x

That means ---> isolate the variable x

Multiply in cross

[tex]5(21)=x(7)[/tex]

[tex]105=7x[/tex]

Divide by 7 both sides

[tex]105/7=7x/7[/tex]

[tex]15=x[/tex]

Rewrite

[tex]x=15[/tex]
