Question

-5(-x - 1) + 4x – 1= 49
solve for x

Answer 1

`\huge \boxed{x=5}`

Explanation:

`{\Large -5(-x - 1) + 4x -1= 49}`

Expand brackets.

`5x+5+ 4x -1= 49`

Combine like terms.

`9x+4=49`

Subtract 4 from both sides.

`9x+4-4=49-4`

`9x=45`

Divide both sides by 9.

`\displaystyle (9x)/(9) =(45)/(9)`

`x=5`

Answer 2

x=5

Explanation:

-5(-x - 1) + 4x – 1= 49

Distribute

5x +5 +4x -1 = 49

Combine like terms

9x +4 = 49

Subtract 4 from each side

9x+4-4 = 49-4

9x = 45

Divide by 9

9x/9 =45/9

x = 5
