Solv for x for all of these 1. 3x+6=21 2. 33=7x-9 3. 28=7+x need to know now please help !!!!!!

-Dominant- [34]

Answer:

<h3> $\boxed{ \sf{ \bold{1. \: \: \: x = 5}}}$ </h3>

$\boxed{ \sf{ \bold{2. \: \: x = 6}}}$

$\boxed{ \bold{ \sf{3. \: \: x = 21}}}$

Step-by-step explanation:

1. $\sf{3x + 6 = 21}$

Move constant to right hand side and change its sign

⇒ $\sf{3x = 21 - 6}$

Subtract 6 from 21

⇒ $\sf{3x = 15}$

Divide both sides of the equation by 3

⇒ $\sf{ \frac{3x}{3} = \frac{15}{3} }$

Calculate

⇒ $\sf{x = 5}$

--------------------------------------------------------

2. $\sf{33 = 7x - 9 }$

Swap the sides of the equation

⇒ $\sf{7x - 9 = 33}$

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

⇒ $\sf{7x = 33 + 9}$

Add the numbers

⇒ $\sf{7x = 42}$

Divide both sides of the equation by 7

⇒ $\sf{ \frac{7x}{7} = \frac{42}{7} }$

Calculate

⇒ $\sf{x = 6}$

---------------------------------------------------------

3. $\sf{28 = 7 + x}$

Swap the sides of the equation

⇒ $\sf{7 + x = 28}$

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

⇒ $\sf{x = 28 - 7}$

Subtract 7 from 28

⇒ $\sf{x = 21}$
