Question

1200-5(3x+30)=600 show the steps to solve this problem

Answer 1

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{x = 30}}}}}$

Step-by-step explanation:

$\sf{1200 - 5(3x + 30) = 600}$

Distribute 5 through the parentheses

$\dashrightarrow{ \sf{1200 - 15x - 150 = 600}}$

Subtract the numbers: 150 from 1200

$\dashrightarrow{ \sf{ - 15x + 1050 = 600}}$

Move 1050 to right hand side and change it's sign

$\dashrightarrow{ \sf{ - 15x = 600 - 1050}}$

Subtract 1050 from 600

$\dashrightarrow{ \sf{ - 15x = 450}}$

Divide both sides of the equation by -15

$\dashrightarrow{ \sf{ \frac{ - 15x}{ - 15} = \frac{ - 450}{ - 15} }}$

Calculate

$\dashrightarrow{ \sf{x = 30}}$

Hope I helped!

Answer 2

Answer:

x=+30

Step-by-step explanation:

1200-5(3x+30)=600

We move all terms to the left:

1200-5(3x+30)-(600)=0

We add all the numbers together, and all the variables

-5(3x+30)+600=0

We multiply parentheses

-15x-150+600=0

We add all the numbers together, and all the variables

-15x+450=0

We move all terms containing x to the left, all other terms to the right

-15x=-450

x=-450/-15

x=+30
