REGARDS MRRYAN

 

lol u want ppl to do ur math homework lol

 

wuts wrong with that?

and woh ses its maths homework

 

1.x=2and2/3
2.x=14

 

Okay, wait a minute and ill solve them, were in this part in our book too

1. 3x + 7 = 15
3x = 8
:3 :3
x = 2 2/3 (2, 66)

2. 4(x-7) = -3
4x - 28 = -3
+28 +28
4x = 25
:4 :4
x = 6,25

3. 9 - 4x = 43
-4x = 34
*-1 *-1
4x = -34
:4 :4
x = -8,5

If u want me to do the others too just pm.

 

angel method? of them please well method for no.2

 

I got two for ya. 22 creds I think...even though you might not even send them <_< I need the practice anyway.

#4- x= -3
#5- x= 3

 

i need methods peple not jus answer

 

Ok It would be better if I could do this through an imer. If not ill type them here.

 

The method?
Subtract seven from 7 and 15 to look like 3x=8. Divide both by three and get x=2.66666666666666666
The second is common sense to me.

 

3) x = -.75
4) x = -3
5) x = 3
6) x = .6
7) x = 1
8) x = .5 ; y = -3

 

if u wanan im add me [email protected]

 

I MAKE THEM all ... wait ... i make them ...

 

Hey i solved 3 of them with method?

If u wnat me to explain more, just add me ([email protected])

 

1. 3x + 7 = 15
3x = 15 - 7
3x = 8
x = 8 : 3
x = 2,(6)

2. 4(x-7) = -3
4x - 28 = -3
4x = -3 + 28
4x = 25
x = 25 : 4
x = 6,25

3. 9 - 4x = 4
-4x = 4 - 9
-4x = -5
x = (-5) : (-4)
x = - 1,25

4. 7x+4 = 3x -8
7x - 3x = -8 -4
4x = -11
x = -11 : 4
x = 5,5

5. 4(3x-2) = 7(x + 1)
12x - 8 = 7x + 7
12x - 7x = 7 + 8
5x = 15
x = 15 : 5
x = 3

6. 4(2x + 3) + 3(x-5) = 6(x - 1)
8x + 12 + 3x - 15 = 6x - 6
8x + 3x -6x = -6 -12 + 15
5x = -3
x = -3 : 5
x = -0.6

7. 2x - 7 = 3 - 4x
2x + 4x = 3 + 7
6x = 10
x = 10 : 6
x = 1,(6)

8. 8x - 3y = 13 | x5
6x - 5y = 18 | x(-3)
-----------------------------
40x - 15 = 65
-18x + 15 = -54
-----------------------------
22x / = 11

x = 0.5
3 - 5y = 18
-5y = 18 - 3
-5y = 15
y = -3
