Follow PEMDAS - but backwards.
(Parenthesis, Exponents. Multiplication, Division, Addition, Subtraction)
First SUBTRACT 5 from each side of the equation...
3x/5 + 5 (- 5) = 20 (- 5)
3x/5 = 15
Next MULTIPLY each side by 5...
3x/5 ( • 5) = 15 (• 5)
3x = 75
The third step if you need is to DIVIDE ...
3x ( / 3) = 75 (/ 3)
x = 25

Answer:
[tex]\displaystylex=25[/tex]
Step-by-step explanation:
First, you subtract by 5 from both sides of equation.
[tex]\displaystyle\frac{3x}{5}+5-5=20-5[/tex]
Then, simplify.
[tex]\displaystyle 20-5=15[/tex]
[tex]\displaystyle \frac{3x}{5}=15[/tex]
Multiply by 5 from both sides of equation.
[tex]\displaystyle\frac{5*3x}{5}=15*5[/tex]
Simplify.
[tex]15*5=75[/tex]
[tex]3x=75[/tex]
Divide by 3 from both sides of equation.
[tex]\displaystyle\frac{3x}{3}=\frac{75}{3}[/tex]
Simplify, to find the answer.
[tex]75\div3=25[/tex]
x=25 is the correct answer.
Hope this helps!
