Question

-8 - x = x - 4x
what is x?

Answer 1

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

Explanation:

`\sf{ - 8 - x = x - 4x}`

Collect like terms

⇒
`\sf{ - 8 - x = - 3x}`

Move 3x to left hand side and change it's sign

Similarly, move 8 to right hand side and change it's sign

⇒
`\sf{ - x + 3x = 8}`

Collect like terms

⇒
`\sf{2x = 8}`

Divide both sides of the equation by 2

⇒
`\sf{ (2x)/(2) = (8)/(2) }`

Calculate

⇒
`\sf{x = 4}`

Hope I helped!
