Question

Solve: 2x + 4 = 12. Show your work!

Answer 1

`\boxed{ \bold{ \huge{ \boxed{ \sf{x = 4}}}}}`

Explanation:

`\sf{2x + 4 = 12}`

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

`\dashrightarrow{ \sf{2x = 12 - 4}}`

Subtract 4 from 12

`\dashrightarrow{ \sf{2x = 8}}`

Divide both sides by 2

`\dashrightarrow{ \sf{ (2x)/(2) = (8)/(2) }}`

Calculate

`\dashrightarrow{\sf{x = 4}}`

Answer 2

`x=4`

Explanation:

`2x+4=12`

To solve this equation, first we must minus out(subtract) 4 from both sides of the equation.

`2x+4-4=12-4`

This equals
`2x=8`

Now we will make this into a fraction and divide the sides by 2.

`(2x)/(2)` equals to
`(8)/(2)`

Now we got an answer!

`x=4`

Hope this helps!
