Question

×+4+×=20 solve for ×

Answer 1

`\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!

Answer 2

`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!
