Question

The first and second steps to solve the equation 3x/5+5=20

Answer 1

`\displaystylex=25`

Explanation:

First, you subtract by 5 from both sides of equation.

`\displaystyle(3x)/(5)+5-5=20-5`

Then, simplify.

`\displaystyle 20-5=15`

`\displaystyle (3x)/(5)=15`

Multiply by 5 from both sides of equation.

`\displaystyle(5*3x)/(5)=15*5`

Simplify.

`15*5=75`

`3x=75`

Divide by 3 from both sides of equation.

`\displaystyle(3x)/(3)=(75)/(3)`

Simplify, to find the answer.

`75/3=25`

x=25 is the correct answer.

Hope this helps!

Answer 2

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
