Question

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

Answer 1

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 2

Answer:

$\displaystylex=25$

Step-by-step explanation:

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

$\displaystyle\frac{3x}{5}+5-5=20-5$

Then, simplify.

$\displaystyle 20-5=15$

$\displaystyle \frac{3x}{5}=15$

Multiply by 5 from both sides of equation.

$\displaystyle\frac{5*3x}{5}=15*5$

Simplify.

$15*5=75$

$3x=75$

Divide by 3 from both sides of equation.

$\displaystyle\frac{3x}{3}=\frac{75}{3}$

Simplify, to find the answer.

$75\div3=25$

x=25 is the correct answer.

Hope this helps!
