Question

4x + 7 = 2x + 19. I know the answer is 6, I need to know how.

Answer 1

Answer: ⇒ x=6

_______________________________________________________

Step-by-step explanation:

First you had to subtract by 7 from both sides of equation.

$4x+7-7=2x+19-7$

Simplify.

$4x=2x+12$

Then you had to subtract by 2x from both sides of equation.

$4x-2x=2x+12-2x$

Simplify.

$2x=12$

Divide by 2 from both sides of equation.

$\frac{2x}{2}=\frac{12}{2}$

Simplify it's should be the right answer.

$\frac{12}{2}=6$

$x=6$

Answer 2

4x + 7 = 2x + 19

First subtract 7 from both sides:

The 7 will cancel out .

19 - 7 = 12

4x = 2x + 12

Next you want to subtract 2x from both sides:

The 2 will cancel out.

4 - 2 = 2x

2x = 12

Finally you are going to divide by 2 on both sides:

The 2 cancels out.

12/2 = 6

So that is how you get 6.
