5x + 7 = 3x - 5

First, subtract 3x from both sides.
5x = 7 - 3x = -5
Second, keep the 7 and subtract the 5x - 3x to get 2x.
2x + 7 = -5
Third, subtract the 7 from both sides.
2x = -5 - 7
Fourth, simplify -5 - 7.
2x = -12
Fifth, take the 2 and divide it on both sides, leaving just x in its place.
x =  -\frac{12}{2}
Sixth, since 6 goes into 2 to get 12, simplify the fraction to 6.
x = -6

Answer: x = -6

Crank

Answer:

<u>Step 1:  Find the x</u>

2x + 5:  Solve

2x + 5 - 5 = 0 - 5

2x / 2 = -5 / 2

x = -5/2

3x + 15:  Solve

3x + 15 - 15 = 0 - 15

3x / 3 = -15 / 3

x = -5

Serenity has a toy car collection. She keeps some in a display case and the rest on the
True [87]

If 74% are in the display, then 100% - 74% = 26% are hung on the wall.

This means 104 cars is 26% of her collection.

To find the total collection divide the number on the wall by the percentage of the collection:

104/0.26 = 400

The total number of her collection is 400 cars.

Last year Ali biked c miles. This year, he biked 261 miles. Using c write an expression for the total number of miles he biked
Bingel [31]
The total amount Ali biked was over two years. To find that amount, you add the amount he biked each year. Since he biked 261 miles in one year and c miles in the other, the total amount of miles is 261 + c. That would be the expression used to describe the total number of miles.

The perimeter of a rectangle is dependent on the length of each of its sides. Suppose the base of a rectangle is two more than i
FrozenT [24]

Answer:

Knowing that the object is a rectangle, and that the base is 2x the height, you could say that h=height and b=base (and the base is the same as width since the object is a rectangle) then a possible equation you could construct is 2(h+2b)

Step-by-step explanation:

For example, using this equation with numbers may look like the following:

  • 2(h+2b)
  • 2(21+2*21)
  • 2(21+42)
  • 2(61)
  • =122

Hopefully I was able to help you :) I would love to hear some feedback if possible and if you were able to find a simpler way.
