Answer: improper fraction : x= 29/4

Mixed number: x=  7   1/4

Decimal form: x=  7.25

Step-by-step explanation: <em>* x is the shortened of saying 1x *</em>

  1. Add like terms (out of the equation combine +3x and +1x which is<u><em> 4x</em></u>. And combine +2and  -6 which is <u><em> -4 </em></u>) and now the equation is reads                   4x -4= 25
  2. Move the "-4" to the other side pf the equation by Addition Property of Equality  4x -4 = 25                                                                                              .                   +4    +4                                                                                                    .                 4x    = 29
  3. Then, separate the 4 from the x to get it by itself by Dividing 4 into 4x . *Remember what you do to one side of the equation do to other side*       4x/4 = 29/4                                        
  4. The answer now depends what the teacher wants if she want it to stay as an improper fraction it will be 29/4 if it wanted in Mixed number its   7 and 1/4 and if its necessary to have in decimal form its 7.25.

Answer:

x= 7.25

Step-by-step explanation:

3x+2+x-6=25

Step 1- Add the variables

4x+2-6=25

Step 2- Add to both sides

4x+2-6= 25

       +6   +6

Step 3- Subtract to both sides

4x+2= 31

   -2     -2

Step 4- Divide to both sides

<u>4x</u>=<u>29</u>

4    4

x=7.25

Alex787 [66]

Answer:

z = 5*(1/2)

z = 5/10

---

time switching classes:

w = 7/10

---

y - 6x - z - w = 0

6x = y - z - w

x = (y - z - w)/6

x = (76/10 - 5/10 - 7/10)/6

x = (76 - 5 - 7)/(10*6)

x = (64)/(10*6)

x = (2*2*2*2*2*2)/(2*5*2*3)

x = (2*2*2*2)/(5*3)

x = 16/15

x = 1.0666666666

---

check:

y = 7 + 3/5

y = 7.6

z = 1/2

z = 0.5

w = 7/10

w = 0.7

y - 6x - z - w = 0

6x = y - z - w

x = (y - z - w)/6

x = (7.6 - 0.5 - 0.7)/6

x = 1.0666666666

answer:

z = 5*(1/2)

z = 5/10

time switching classes:

w = 7/10

y - 6x - z - w = 0

6x = y - z - w

x = (76 - 5 - 7)/(10*6)

x = (64)/(10*6)

x = (2*2*2*2*2*2)/(2*5*2*3)

x = (2*2*2*2)/(5*3)

x = 16/15
