Question

3x - x = 12 , x+8x=72 , 9x+x-9x=5 , 4x+3x-7x=6 , 5x+ 2x=84 , 12x-4x =3248 , 17y-y=16165 , y+19y=4040 уровнение решите плизз

Answer 1

1) 3x-x=12, 2x=12, x=6.
2) x+8x=72, 9x=72, x=8.
3)9x+x-9x=5, x=5.
4) нельзя, т.к. 7x-7x=0, а 0 не равен 6.
5)5x+2x=84, 7x=84, x=12.
6)12x-4x=3248, 8x=3248, x=406
7)17y-y=16165, 16y=16165, y=16/16165
8) y+19y=4040, 20y=4040, y=202

Answer 2

1)3х-х=12
2х=12
х=12:2
х=6
2)х+8х=72
9х=72
х=72:9
х=8
3)9х+х-9х=5
х=5
4)4х+3х-7х=6
0х=6(нет решения,поскольку на ноль делить нельзя)
5)5х+2х=84
7х=84
х=84:7
х=12
6)12х-4х=3248
8х=3248
х=3248:8
х=46
7)17у-у=16165
16у=16165
у=16165:16
у=1010,3
8)у+19у=4040
20у=4040
у=4040:20
у=20

Answer 3

Solving the Equations

To solve the given equations, let's go through each one step by step.

1. 3x - x = 12 Combining like terms, we have: 2x = 12 Dividing both sides by 2, we get: x = 6

2. x + 8x = 72 Combining like terms, we have: 9x = 72 Dividing both sides by 9, we get: x = 8

3. 9x + x - 9x = 5 Combining like terms, we have: x = 5

4. 4x + 3x - 7x = 6 Combining like terms, we have: 0x = 6 Since any number multiplied by 0 is always 0, this equation has no solution.

5. 5x + 2x = 84 Combining like terms, we have: 7x = 84 Dividing both sides by 7, we get: x = 12

6. 12x - 4x = 3248 Combining like terms, we have: 8x = 3248 Dividing both sides by 8, we get: x = 406

7. 17y - y = 16165 Combining like terms, we have: 16y = 16165 Dividing both sides by 16, we get: y = 1010.3125

8. y + 19y = 4040 Combining like terms, we have: 20y = 4040 Dividing both sides by 20, we get: y = 202

Solutions to the Equations

The solutions to the given equations are as follows:

1. 3x - x = 12 x = 6

2. x + 8x = 72 x = 8

3. 9x + x - 9x = 5 x = 5

4. 4x + 3x - 7x = 6 This equation has no solution.

5. 5x + 2x = 84 x = 12

6. 12x - 4x = 3248 x = 406

7. 17y - y = 16165 y = 1010.3125

8. y + 19y = 4040 y = 202

Please note that the solutions to equations 7 and 8 involve decimal values.
