Question

-5(-x - 1) + 4x – 1= 49 solve for x

Answer 1

Answer:

x=5

Step-by-step 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

Answer 2

Answer:

$\huge \boxed{x=5}$

Step-by-step 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.

$\displaystyle \frac{9x}{9} =\frac{45}{9}$

$x=5$
