Question

8k+2= -22
x+1=-3-x
7-3y=y+15
2w-3+-w-15

Answer 1

8k+2=-22
8k+2-2=-22-2
8k=-24
k=-3

x+1=-3-x
x+1-1=-3-1-x
x=-4-x
x+x=-x+x-4
2x=-4
x=-2

7-3y=y+15
-3y+7-7=y+15-7
-3y=y+8
-3y-y=8
-4y=8
-4y/-4=8/-4
y=-2

2w-3+w-15
3w-18=0
3w-18+18=0+18
3w=18
w=6

Answer 2

These are all first degree equations and are very simple to solve, so lets begin.
8k + 2 = -22 (first of all we have to group non incognite with non incognite and incognite with incognite)
8k = -22 - 2 (I put the 2 to the other side of the equation and then its sinal change)
8k = -24
k = -24 / 8 (the same goes here, the 8 was multiplyng and it goes to the other side dividing. )
k = -3

x + 1 = -3 - x
2 x = -4
x = -2

7 - 3y = y + 15
-4 y = 8
y = -2

2w - 3+-w - 15
this last one has +- and i dont know what you wanted to say with this. I will solve in 3 different ways. Check if one these is the one you wanted.

2 w - 3 + w - 15 = 0
3w = 18
w = 6
or
2 w - 3 - w - 15 = 0
w = 18
or
2w - 3 = w - 15
w = -12

I hope I helped you!

Answer 3

8k + 2 = - 22

8k + 2 - 2 = - 22 - 2

8k = - 24

8l/8 = - 24/8

k = - 24/8

k = - 3

- - - - - - -

x + 1 = 3 - x

x + 1 + x = 3 - x + xx

2x + 1 = 3

2x + 1 - 1 = 3 - 1

2x = 2

2x/2 = 2/2

x = 2/2

x = 1

- - - - - - -

7 - 3y = y + 15

7 - 3y - y = y + 15 - y

7 - 4y = 15

7 - 4y - 7 = 15 - 7

- 4y = 8

- 4y / - 4 = 8 / - 4

y = 8/- 4

y = - 2

- - - - - - - -

2w + 3 + w - 15 = 0

3w - 12 = 0

3w - 12 + 12 = 0 + 12

3w = 12

3w/3 = 12/3

w = 12/3

w = 4

Answer 4

8k+2= -22

subtract 2 for both sides
8k = -24

divide 8 for both sides
k = -3
--------------
7-3y=y+15

add 3y for both sides
7 = 4y + 15

subtract 15 for both sides
-8 = 4y

divide 4 for both sides
y = -2
-----------------------
x+1=-3-x

add x for both sides
2x + 1 = -3

subtract 1 for both sides
2x = -4

divide 2 for both sides
x= -2
-------------------
2w-3+-w-15
this can not be solve because it is not set equal to something

can only simplify

w - 18

Answer 5

1. Solve for k....8k + 2 = -22

First: combine "like" terms - subtract 2 from both sides (when you move a term to the opposite side, always use the opposite sign)....

8k + 2 - 2 = -22 - 2
8k = -22 - 2
8k = -24

Sec: isolate "k" on one side - divide both terms by "8"....

8k/8 = -24/8
k = -24/8
k = - 3

2. Solve for x.... x + 1 = - 3 - x

First: combine the x-variables > add "x" with both sides....

x + x + 1 = - 3 - x + x
x + x + 1 = - 3
2x + 1 = - 3

Sec: subtract 1 from both sides....

2x + 1 - 1 = - 3 - 1
2x = - 3 - 1
2x = - 4

Third: isolate "x" on one side - divide both terms by "2"....

2x/2 = - 4/2
x = - 4/2
x = - 2

P.S. Follow the steps from the previous 2 problems in order to complete the last 2.

Answer 6

1) 8k+2= -22
or, 8k= -22-2
or, k= -24/8
or, k= -3

2) x+1= -3-x
or, x+x= -3-1
or, 2x= -4
or, x= -2

3)7-3y=y+15
or, 3y+y=7-15
or, 4y= -8
or, y= -2

4) 2w-3+-w-15 = w-18

Answer 7

8k+2 = -22
8k = -24
k = -3

x+1 = -3-x
2x = -4
x = -2

well, u can do the rest!!!

Answer 8

1.8k= -24
So, k= -3.

2.2x= -2
So, x= -1.

3. -4y=8
So, y= -2.

4. w-18=0
So, w=18.
