1:6x+6=0
2:-3x+9=6
3:=5x+4=-6
4:-257=25x-50
5:90=20x-10

Answer 1

Explanation:

1:6x+6=0

6x=-6

x=-6/6

x=-1

2:-3x+9=6

-3x=6-9

-3x=-3

x=-3/-3

x=-1

3: 5x+4=-6

5x=-6-4

5x=-10

x=-10/5

x=-2

4: -257=25x-50

-257+50=25x

-207=25x

x=-207/25

5: 90=20x-10

90+10=20x

100=20x

x=100/20

x=5

Answer 2

1: x = -1

2: x = 1

3: x = -2

4: x = -207/25

(Double check if the question you posted was correct, if it was, then this is the answer you should get) ( maybe it was -25 instead of -257, check just in case, in that case, the answer should be x = 1)

5: x = 5

Explanation:

1: 6x + 6 = 0

dividing both sides by 6, we get,

x + 1 = 0

x = -1

2:-3x+9=6

Dividing both sides by 3, we get,

-x + 3 = 2

3 - 2 = +x

(we have added +x to both sides so on left side -x+x =0 and so on with -2 as well)

1 = x

x = 1

3:5x+4=-6

Subtracting 4 from both sides,

5x + 4 - 4 = -6 - 4

5x = -10

dividing both sides by 5,

x = -10/5

x = -2

4:-257=25x-50

Adding 50 to both sides,

-257 + 50 = 25x -50 + 50

-207 = 25x

dividing both sides by 25, we get,

-207/25 = (25x/25)

-207/25 = x

x = -207/25

5:90=20x-10

Dividing both sides by 10,

90/10 = (20x - 10)/10

9 = 20x/10 - 10/10

9 = 2x - 1

adding 1 on both sides,

10 = 2x

dividing by 2 on both sides,

10/2 = x

x = 5
