Question

please help me find out the answer do all​

Answer 1

Answer:

1. 4(x -2) = 2x +10

=> 4x - 8 = 2x + 10

4x -2x = 10 +8

2x = 18

x = 18/2

x = 9

_____________

2. 8(x + 11) = 100

=> 8x + 88 = 100

8x = 100-88

8x = 12

x = 12/8

x = 2

_____________

3. 5-x /2 = 10

=> 5 -x /2 × 2 = 10 × 2

5-x = 20

x = 20/5

x = 4

_____________

4. 3x - 5 = 2x + 4

=> 3x -2x = 4 +5

1x = 9

x = 9

______________

5. 1/3 x -5 = x + 2

=> 1x/ 3 - 5 = x + 2

x /3 -5 = x + 2

x /3 -5 + 5 = x + 2 + 5

x/3 = x + 7

x/3 × 3 = x + 7 × 3

x = x + 21

2x = 21

x = 21

que 4th

1. 6 is a root of 3y = 18

=> y = 18/3

y = 6

Yes, 6 is a root

__________________

2. -9 is a root of x -9 = 0

=> x -9+ 9 = 0+9

x = 9

No, -9 is not a root

________________

3. -2 is a root of p² -9 = 0

=> p² -9 +9 = 0+ 9

p² = 9

p = √9

p = 3

No, -2 is not the root

___________________

4. 3 is a root of 6x = 18

=> x = 18/6

x = 3

Yes, 3 is a root of 6x = 18

___________________

Que. 5th

1. -11 = 12 + x

=> 12 + x = -11

12 + x + 11 = -11 +11

23+ x

x = 23

_____________

2. x/ 5 + x/2 = 7

=>x × 2 + x × 5 = 7

2x + 10 = 7

2x + 10 - 10 = 7 - 10

2x = 3

x = 3/2

_______________

3. p/6 = 2

=> p/6 × 6 = 2 × 6

p = 12

________________

4. 40 = 5(2 + y)

=> 40 = 10+y

10 + y = 40

10 -10 + y = 40 -10

y = 30

_________________

5. 2(x + 6) = 12

=> 2x + 12 = 12

2x + 12 - 12 = 12 - 12

2x = 0

x = 0/2

x = 0
