Question

-17 + 2x = 4(2 + x) – 1x

Answer 1

• 
  `\sf x=-25`

Explanation:

`\sf -17 + 2x = 4(2 + x) - 1x`

■ First, multiply 1 * x= x

`\sf -17+2x=4\left(2+x\right)-x`

■ Now, Expand:- Apply Distributive Property.

`\sf -17+2x=8+4x-x`

■ Combine like terms:

( 4x-x) ➺ 3x

`\sf -17+2x=8+3x`

■ Add 17 to both sides:

`\sf -17+2x+17=8+3x+17`

`\sf 2x=3x+25`

■ Subtract 3x to both sides:

`\sf 2x-3x=3x+25-3x`

`\sf -x=25`

■ Divide both sides by -1:

`\sf \cfrac{-x}{-1}=\cfrac{25}{-1}`

`\sf x=-25`
