Add 4 to each side to get -5x=4+?. then divide each by 5, -x=(4+?)/5 then make x positive and 4/5 negative! x=-(4+?)/5. Hope this helped!

If you want to solve for x
-5x-4=?
add 4 to both sides
-5x=4+?
divide both sides by -5
x=(4+?)/-5
x=-(4+?)/5

Meredith solved a quadratic equation. Her work is shown below.
Damm [24]

Answer:

Step 2

Step-by-step explanation:

Meredith made a fatal mistake or error in step 2;

Any quadratic problem will always have two solutions. Therefore since, we only have one solution here, it is wrong. The mistake was incurred in step 2;

  From the given problem ;

    <u> Wrong                                                  right</u>

    2(x + 4)² = 242

    (x + 4)² = 121     Step 1  

     x+4=11              Step 2                  x + 4  = ± 11

     x  = 7                Step 3                  x + 4  = 11 or x + 4  = -11

                                                           x  = 11- 4     or    x  = -11 - 4

                                                           x  = 7 or -15

Solve 4x - 3 = 18. Round to the nearest thousandth.
lorasvet [3.4K]

Answer:

x=5.250

Step-by-step explanation:

We have been given an equation 4x-3=18. We are asked to solve our given equation.

First of all, we will add 3 to both sides of our equation.

4x-3+3=18+3

4x=21

Now, we will divide both sides of our equation by 4.

\frac{4x}{4}=\frac{21}{4}

x=5.25

Upon rounding our answer to nearest thousandth (3 places after decimal) we will get,

x=5.250

Therefore, the solution for our given equation is x=5.250.
