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!
