Answer:

x = 4/7

Step-by-step explanation:

5/3 x = 20/21

Multiply by 3/5 on each side to isolate x

3/5 *5/3 x = 20/21 * 3/5

x = 20/21 * 3/5

Rewriting the right hand side

x = 20/5 * 3/21

x =4 * 1/7

x = 4/7

you could write it as:
[tex] \frac{5x}{3} = \frac{20}{21 } [/tex]
Cross multiply
[tex]105x = 60[/tex]
divide 105 on both sides
Answer:
[tex]x = \frac{60}{105} [/tex]
[tex]x = \frac{4}{7} [/tex]
