Answer:

$\boxed{ \bold{ \huge{\boxed{ \sf{x = 8}}}}}$

Explanation:

$\sf{x + 4 + x = 20}$

Collect like terms

$\longrightarrow{ \sf{2x + 4 = 20}}$

Move 4 to right hand side and change it's sign

$\longrightarrow{ \sf{2x = 20 - 4}}$

Subtract 4 from 20

$\longrightarrow{ \sf{2x = 16}}$

Divide both sides by 2

$\longrightarrow{ \sf{ (2x)/(2) = (16)/(2) }}$

Calculate

$\longrightarrow{ \sf{x = 8}}$

Hope I helped!

Best regards! :D

Answer:

x=8

Explanation:

So we have the equation:

x+4+x=20

And we want to solve for x.

First, combine like terms on the left side:

2x+4=20

Subtract 4 from both sides:

(2x+4)-4=(20)-4

The left side cancels. Subtract on the right:

2x=16

Divide both sides by 2. The left side cancels again:

x=8

So, the value of x is 8.

And we're done!
