Question

- 4(x + 5) = 5(x - 4)

Answer 1

X=0

Explanation:

−4(x+5)=5(x−4)

Use the distributive property to multiply −4 by x+5.

−4x−20=5(x−4)

Use the distributive property to multiply 5 by x−4.

−4x−20=5x−20

Subtract 5x from both sides.

−4x−20−5x=−20

Combine −4x and −5x to get −9x.

−9x−20=−20

Add 20 to both sides.

−9x=−20+20

Add −20 and 20 to get 0.

−9x=0

Answer 2

• 
  `\sf x=0`

Explanation:

`\sf - 4(x + 5) = 5(x - 4)`

Expand :-

• 
  `\sf -4x-20=5x-20`

Add 20 to both sides:-

• 
  `\sf -4x-20+20=5x-20+20`

Simplify:-

• 
  `\sf -4x=5x`

Subtract 5x from both sides :-

• 
  `\sf -4x-5x=5x-5x`

Simplify:-

• 
  `\sf x=0`
