Question

Solve this equation 4x-4=2x+8

Answer 1

`x=6`

Explanation:

`4x-4=2x+8`

`\hookrightarrow` Add 4 to both sides:

`\longmapsto 4x-4+4=2x+8+4`

`\longmapsto 4x=2x+12`

`\hookrightarrow` Subtract 2x from both sides:

`\longmapsto x-2x=2x+12-2x`

`\longmapsto2x=12`

`\hookrightarrow` Divide both sides by 2:

`\longmapsto(2x)/(2)=(12)/(2)`

`\longmapsto x=6`
