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:

\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

Which additional information is needed to solve this problem?
liq [111]
Hi there!

The answer is B.
the cost of the game.

We need to know the cost of the game in order to find out how many weeks John has to save money. If we don't know this price, we'll never know whether John has saved enough money.

We can find out the total amount of money John can save in 1 week (so A. is not the answer). The amount of money John earns per hour doesn't matter to answer the question (so C. is wrong).

~ Hope this helps you!
